I appreciate your effort, however I really dont think this should be titled "HOW to stock a lab" - more like a lesson on common household items that contain said lab chemicals. My concern with this is that everything is highly impure! More the metals - most of which are contaminated with highly reactive contaminants/additives - meaning your workups may not kill you but you are guaranteed to get a product-ish with a shit ton of side reaction impurities.
@MysteryBowl Calm yourself. I'm aware that you are supposed to add acid to water, not water to acid. Sorry I didn't explicitly state that in the safety section. I do take offense to your highly negative attitude. If you have specific criticisms I can try to address them. These experiments, however crude, were what inspired me to pursue an undergraduate (and soon a graduate) degree in chemistry at a very good university. Ask yourself - should you really be trolling around on youtube?
@zcuttlefish Who's trolling? Neutralizing a chemical burn is the obvious course of action - AND IT IS COMPLETELY INCORRECT. The reaction between acid and base is exothermic, and will add thermal burns to the chemical burn. Instead, flush the burn with cold water for at least 5 minutes. If you really are an undergraduate in chemistry then you should know that. You're giving bad and unsafe advice. Leave the teaching to the teachers.
@MysteryBowl You are correct that flushing with water is the standard procedure, but have you ever added water to sulfuric acid? The process is exothermic. Interestingly enough, the reaction between baking soda and vinegar is endothermic. I'm not sure if the reaction between sulfuric acid and baking soda is endothermic, but I doubt it would be much worse than adding water. I'm not suggesting people neutralize acid burns with sodium hydroxide. Neutralizing with bicarb + flushing can't hurt.
Meaning no disrespect, but you don't appear to have a strong understanding of the physical properties and makeup of the materials you list. If this is the case, should you really be mucking around with chemistry?
zinc can be found in pennys, any produced in the last decade or 2 are a thin copper shell over a zinc core (copper got too expensive).
You can just nick the copper with a file, hold the penny with pliers or similar and hit it with a propane torch, the zinc will melt and drop out leaving a copper husk. You have to nick the copper though or it will just deform and not seperate.
You know, I'm still very much alive. I'm not sure exactly what you're referring to, but whatever it is, I'm sure your concerns are unfounded. Also, I'm not a "friking idiot" I go to Yale and I'm applying to Grad school in chemistry. So dude, check yourself before you wreak yourself.
@zcuttlefish dude, that's a shitty lab. its really unsafe. i really hope you don't actually use those chemicals for pyrotechnics or whatever. i'm just saying that you shouldn't use chemicals you buy at wallmart because they aren't pure. im pretty sure i have more experience than you. don't be stupid.... ok??
by the way, i don't give a shit about you going to Yale....
Actually, most of those chemicals should be okay. Is it the best lab? no, but it's not really a bad one either. We've used a lot of these chemicals in high school chemistry labs. This is how my chemistry experiments started out. As long as you know what will happen, and you can account for that, you'll be fine.
Also, how do you have more experience than him? proof?
@japanesepoptart ive been doing chemistry and pyrotechnics since i was a little boy. my parents are chemists and my dad worked as a weapon builder in the army. the videos on my channel were filmed a few years ago. i dont post all the shit i do today on you tube because im not allowed to give any info about my current job... im not going to bring any more proof because its a fucking discussion on youtube!
@xX1R0NMA1DENXx Don't mess with the posh kid, you might hurt their well-cultivated ego. Logical fallacy #357, "I am a Yalie, therefore I am TRUTH!" Of course, people must work within their material and financial means, but that doesn't make the kind of impurities of these materials any less of a concern.
solder for tin... are you nuts ? solder is usually an alloy of lead and tin ranging around 50% to each side give and take some,... standard electronics solder has an alloy of 2% silver and then 61/37 tin/lead this is no good for most and then there is the nice bonus of the resin flux... May I suggest to use something else, especially if you are dipping this into any acid... lead salts are quite harmfull...
@klj2503 In retrospect, it wasn't my brightest idea. However, I used the lead free from of solder - I think it was the Sn-Ag-Cu mixture. Tin is higher on the activity series, so it dissolved more readily than the Ag or Cu, and therefore was plated before the others (even though it should in theory be easier to reduce Ag+ or Cu2+). The main thing I should have worried about was creating organotin compounds. This is why i stopped doing this experiment long ago.
Charcoal is not actually carbon, charcoal is a very big combination of different permutations of CnHnOn where n is any number, which is why it burns relatively easy.
Epsom salts is Magnesium Sulphate in a hydrated form. Most of the time, septahydrate. (MgSO4 + 7H2O) It isnt suitable for use in a dessicator or any reaction that calls for anhydrous reactants.
@ChemHandbook Chalk native to my home has as least some calcium carbonate (as it bubbles in the presence of acid and the resulting salt flame tests red). It may contain some calcium sulfate.
One of many things that suck about the education system is that it teaches young students to hate chemistry because of the poor education system(not including private schools). They really don't see the sweet science in chem.
Solder is a vary bad source for lab grade use, It is vary impure. Flux cored or not standard solders have high concentrations of lead (example being common 60/40 solder 60% tin 40% lead) even lead free solder is still limited to around 50 to 60% tin. As for charcoal it is not activated carbon, it is a impure form of carbon in general. As for sulfurdust just ignore that crap, you can buy pure sulfur at CVS or walgreens (most drug stores carry it).
@jaffey2006 why in the heck would you like to make meth it turns you into a brainless freak like if you drank murcury and ate lead.Oh and I don't now how;);)
I would recommend getting Nitrile gloves over Latex as many solvents will easily dissolve Latex. Nitrile gloves will only be a few dollars, at most, more expensive.
You can get zinc and carbon from taking apart a 6 volt battery. When you open it up, there's 4 1.5 volt batteries on the inside. The electrodes are carbon and the casings are zinc. The stuff on the inside of the batteries is manganese dioxide, but it's got a lot of impurities in it.
Hi very good questions. If the measuring cups are pyrex they can stand the temp of the hotplate without cracking. If they are made from normal glass they will crack.
As a precaution however, I try not to cool them rapidly when they are hot.
The respirators don't protect against that much - but they stop particulates and some protect against HCl fumes. May also protect against organic solvents. You can pick one up a lowe's for 20-30 dollars.
No, no . . . Pyrex is a name, not a glass composition. The measuring cups are made of soda lime glass, not borosilicate (heat resistant) so it's probably not safe to put them on the hotplate. I believe they stopped using borosil. for measuring cups in the 1930's!!
@MasterTheJ Something to keep in mind. The heat resistant glass is borosilicate glass. It's commonly called "pyrex glass". Pyrex is a brand. Pyrex lab glass is borosilicate, but not all Pyrex brand items are borosilicate. So I would look on the package to see if it says anything about heat resistance. Personally I would rather just use real lab glass. American Science and Surplus caries bromex brand lab glass which isn't very expensive. You can also find it other websites as well.
one can get potassium hydroxide solution as brand name PEQUA at a Lowes to avoid dissolving it at home which can be a pain. and also potassium nitrate is sold as stump remover
btw zcuttlefish ur like the only one to post a vid on where to get sulphur so props
@imaball Go to a REAL hardware store, like Ace or TrueValue, NOT a mega hardware store like Home Depot or Lowe's. It's called Muriatic acid. I bought a gallon for about $6.00. Call around before you go.
@zcuttlefish is a joke relax bill ny the science guy...my head checked? an your teaching ppl how to make unsafe stuff from ordinary house hold items? sorry for my bad humor but damn lol.... have you ever tried clourine tablents + rubbing alchol inside a 20 oz soda bottle?? fun stuff...
Is there a ready, easily acessable source for Nickel Oxide, Nickel Sulphate, Or Nickel Acetate? Or, for pure nickel itself? I want to do a small amount of nickel plating and commercially available quanties of the chemicals are not cost effective for the small amount of work I want to do..
Almost everything you showed us is impure... these are nice suggestions to start with but if you want to consider home laboratory as your hobby then you must buy pro analysi stuff from companies which specialize in chemicals and laboratory glass.
part of the challenge is making pure reagents via re-crystalization, distillation or other methods. Buying chemicals from supply companies is expensive and often unnecessary unless you want to analyze your product with IR NMR GC or some other method. If you want to shell out the cash that's fine, but half of the fun is figuring out how to turn lead into gold.
one other thing - You can get very accurate results if you have the right kind of scale. I titrated the 20% acetic acid i bought at Lowe's. I calculated the molarity to within less than 1% of the value reported on the bottle with phenolphthalein from a kiddy chemistry set (that means to within 1% of the weight of the mols of acetic acid not the % mass).
It really depends on what you do in your lab. For my needs, a lot of these products didn't do the job. The acetic acid for example - while you may be capable of correctly determining its mass by titration (I hope with a bought burette, not an improvised one), it just has some impurities. If you try synthesize something with it, the product will always be brown or orange. Plus, there are some useful lab reagents that you can't buy or make with bought impure stuff.
In my country, the prices of pure chemicals is 10 times cheaper than in the US. So, I understand the reason for improvising. I tried it - but after much headaches and unsuccessful experiments I just decided to go with pure stuff. And I don't think that this is an appropriate video response, because NurdRage talked about pure chemicals and sites that sell them.
PS. If you think that pure products are only good for NMR, why do all the laboratories (e.g. school laboratories) which do not use NMR have bought and not improvised chemicals?
@YdeckW because things cost money. I think you're missing the point. Also, if you actually read up on the subject you would find that re-crystallization, distillation, and sublimation are very easy and very effective ways of purifying reagents.
@YdeckW Why do schools buy pure chemicals? Because it's easier, the teachers are not paying for the chemicals personally, and they often have some way to analyze the product (something simple like melting point at least). If you have done the reading, I'm not sure why you are pursuing this line of questioning. Just go buy your pure reagents. Arguments on the internet are like the special olympics....
@YdeckW Which country is that you lucky bastard. Chemicals in the US are overpriced if you can even get them, the stupid DEA and homeland security leans on everyone to the point where even crystal iodine is restricted.
@starknife I know right, what places have you found that will accept orders from individuals? United nuclear, makers shed, ebay, and several school science supply houses are all I know.
I would imagine you would be correct, my memory doesnt serve me very well, last time i did it, it was a couple of years back under instruction of a Phd Chemist.
one of the methods i was shown used reflux condensing, im probably getting confused or something as to the exact chemical precursors, and processes involved.
Yeah, esterification of salicylic/2-hydroxybenzoic acid + acetic/ethanoic anhydride, using h2so4 or phos acid as a catalyst.
You are right dude, my chemistry is kind of sucky, im not a chemist though.
Ive made silly mistakes before in some videos on youtube, i really aught to shut my mouth unless i know what i am talking about, my hearts in it my minds on vacation.
Thank you for the help, can i ask what your science background is?
I appreciate your effort, however I really dont think this should be titled "HOW to stock a lab" - more like a lesson on common household items that contain said lab chemicals. My concern with this is that everything is highly impure! More the metals - most of which are contaminated with highly reactive contaminants/additives - meaning your workups may not kill you but you are guaranteed to get a product-ish with a shit ton of side reaction impurities.

You are right dude, my chemistry is kind of sucky, im not a chemist though.
Ive made silly mistakes before in some videos on youtube, i really aught to shut my mouth unless i know what i am talking about, my hearts in it my minds on vacation.
Thank you for the help, can i ask what your science background is?

You are correct, i get mixed up sometimes, sorry.
There are a few methods though, but indeed you could try it the way you just said with the addition of reacting it under reflux.

Man if you only had some salicylic acid to go with that acetic, could make some pure aspirin from scratch.
Great video anyway, ill be checking that book out.
