Purification of Manganese Sulfate

[terawattyear]

Nurdrage, THANK you for making this video. I have been trying to get MnCl2 out of MnO2 (that I got from the same G*****6 vendor you did before I saw you show how bad it is). That stuff was SO iron contaminated I was just stuck. Your method for purifying MnSO4 works for MnCl2 as well. I'm looking at my clean pink MnCl2 right now! Funny, isn't it, the things that make a nurd happy?

[NurdRage]

@terawattyear thanks for watching! its good to know people still watch and appreciate these more obscure synthetic videos. :)

[elementcollector1]

@NurdRage My MnCl2 is contaminated with something very strange. I started with a green HCl acid (which is already weird) and got a darker green mix. On addition of NaOH, a brown precipitate settled out. I have no idea what this is, or if it's even a manganese compound. How do I test for this?

[JChem92U]

Why do you use paper towels as filters instead of coffee filters or filter paper? You noted on your video on making ammonium nitrate that the paper towels left impurities in the ammonium nitrate. It seems to me that paper towels offer much lower quality for only a small saving in price. Not to mention it doesn't look very professional. Is there a special reason you use paper towels?

[NurdRage]

@JChem92U Precisely BECAUSE its unprofessional and cheap and what most people would probably try it. By showing people the screw-ups and mistakes they'll likely make, they can anticipate them and work around them. If you notice in my TCPO video i used glass frit funnels, far superior to any filter paper. But i try to avoid using that because most people don't have and can't buy glass fritted funnels. Instead they use paper towels.

So i will too. :)

[TeHKasperek]

I wanna be your lab assistant!

[toothpick93]

i wanna make manganese chloride but it is also contaminated iron, would this method of purifying the manganese salfate also work with the chlorides?

[starshock01]

could you initially wash with sodium bicarbonate to neutralize the acid before adding the strong base?

[hjvdryst]

I have Mn ore(40%Mn) with high Fe levels (16%Fe), I am looking for a way to get most of fe out of ore.

[lexichronicle2]

@hjvdryst I have just finished trying the Nurds hydroxide method on solutions so heavily contaminated they were brown / yellow

I now have pink solid.

Works beautifully and if so simple - no fine pH control, no gassing, no special chemicals (just some base and filter papers)

I was using the chloride salts and KOH

I made some video clips to show others it being repeated, so I'll try to upload a reply to show how effective it is - it really is a good idea

[dominic14061995]

can this method work for manganese chloride?

[yugioh1443]

wow i feel smart now

[1RadicalOne]

What would I do if I wanted to make large copper sulfate crystals from copper metal? Assume I have access to sulfuric acid and cheap "foundational" chemicals (like NaOH, Mg, etc)

[vmelkon]

@1RadicalOne You need 2 copper electrodes. Dip them in the H2SO4 and pass some current, something like 12V or less. The solution turns blue. Then let it dry very slowly.

[1RadicalOne]

Ah. Thank you. :)

[anitalindawaty]

You use MnO2, how about if we use Mn Ore, Mn content around 55%. We still use the same composition: 30 gr oxalic acid, 300 gr water & 13 gr H2SO4, OR we can add more H2SO4? more oxalic acid? thanks

[discaras]

can the same method be used to purificate manganese chloride

?

[lexichronicle2]

@discaras yes

I have been working with a big batch of the chlorides and they were absolutely FILTHY with iron chloride

I used KOH, since I have more of that to hand than NaOH, but his hydroxide idea works REALLY well for the simplicity of the equipment and chemicals

I will try to upload a video of it later if my computer can handle editing it

[Eh302]

you lost me when you started talking about science =P but looks cool!

[blinking801]

Hey nurds take a look at the video in Science Daily about "metal rubber". Pretty interesting!

[slateflash]

Now i can see the pink colour:D

[hurcule911]

wondering do conduct specific experiments in different types of glass containers? (if the glass has a direct affect to the experiment)

[nikitofin]

you have the best voice in the world

[derkozten]

Nice Mn chem... gotta love transition metals

[jonbaz]

great video

[waskaman94]

what is the use of mno2 electrodes? i noticed in your tags you put chlorate and perchlorate cell... is that what u use it for?

[blinking801]

Really like that you are putting the formulas in your videos now.

[YdeckW]

This is a very very good method. Did you think it up? If you did, than I hold my hat up to you.

[pacificcloud]

Way over my head, but it looks cool! Love your nerd voice! 5/5

[PittyPaintUser]

Is it possible to skip the overnight prosess by adding some low percentage hydrogenperoxide, or will this convert the Mangenesesulfate(II) to Manganesedioxde(IV)?

[Sheynan55]

thx nurdrage! great video!

[xEllykinzorsopz]

Okay, I have no idea what you did but it sounded so awesome and interesting that I subscribed - I am definitely going to learn this. FUN!!

[roflcopter2225]

just a suggestion, but when there is a redox reaction, can you show the half reactions in your video?

[Pyroxylin]

Hey Nurdrage,Can you make a video in making SIlicon with Silica dioxide?

[SatansBaby1]

Great vid!

[Masterkan8]

couldnt you use a magnetic stir to get rid of the iron then recrystallization to pure it?

im just tossing that out there lol

[JehuMcSpooran]

@Masterkan8

I don't think so as the Iron would be present as Iron Sulfate which is non-magnetic. Please correct me if I'm wrong though

[NurdRage]

@Masterkan8 if that were true then you'd be able to

remove iron from your blood with a magnet.

[Masterkan8]

@NurdRage oh ok well you can remove iron from iron rich food that way too but i didnt know sorry lol

[lamboroghini]

@NurdRage I was thinking that you could use K3 EDTA that you could pick up at a vetrinarian. Thats what they use to getheavy metals out of blood so amybe it would percipitate off or sink to the bottom of the beaker.

[NurdRage]

@lamboroghini EDTA would also chelate manganese itself, in addition the complex with iron would still be soluble, so it wouldn't work to purify the manganese sulfate. Also, gram for gram, sodium hydroxide is cheaper :)

[cheeseboat15]

Very nice! *****

[killer2611]

awesome

i should of taken chemistry :(

[Pliskkenn]

Another great vid.

[ILikeWeatherGuy]

wooo i dont get a thing but its awsme and i watch it anyway! ;D

[ea1475mdma]

I really enjoy your videos. :)

[kainih]

geeks...

[jpthecreaton]

@kainih fuck off...hail to the geek!!!

[elfspader]

um y is ur voice so deep

[schaefshootr]

hey nerd,,, is that your real voice?

[xXdenhartXx]

Thanks for another great video.

[Sillybillydilly]

That is an awesome video.

[Pentagram133]

Fantastic

[Danshak555]

Very informative, good job.

[sempeRxLiber]

when ever we take out the precipitate of a solution we end up letting it dry over night, is there a reason you didn't?

[APotatoWithAGun]

Is it smarter to do back flips when Jesus is watching you?

[NurdRage]

@APotatoWithAGun

Dude walked on water, i don't think he's

going to care if you can do a back flip.

He'll be like: "LAME, look what i can do!"

[coilsinamotor]

@NurdRage ya gosh potato with a gun Jesus is like AWSOME and back flips r not jk

[coilsinamotor]

@coilsinamotor wasnt at nurd rage

[microman9101]

your cool?

[milotickz]

Can you make a video of making sodium hydroxide when you have a chance?

[maniamme2]

Chemistry is arguably one of the hardest things to learn.

[kiepskipolak]

can you show us how to make acetone peroxide

[ikcti]

NurdRage FTW.

[g00nsessan]

lol i love transcribe audio its so funny!

[chase1146]

your kinda helping me in one of my classes in school

[Hexpigge]

awesome :D

[Hexpigge]

less :) Coffee filter only takes bigger particles of things... :)

[Ankeladden]

Great video NurdRage crew!!

[CrAzYcArNiE08]

comment

[antiswattt3]

i just love the look of a clear liquid that youve worked for to make clear (:

[anchor425]

ive really enjoyed the last year or so..or 2 or 3 ...lol...hell whos counting......your shows great.....best part is if ya wanna it can be on air every season...beats hell outa tv science guy stuff...keep up the good work....after the upcoming revolution... kids will have real chemi sets to play with again....and guys like you will be looked back upon as heros...hummmm?...i look around.. and your the only chem teacher hero online...damn!...guess your it boss! im impressed!....lol..much love...

[OrganicWebhead]

Great video =)

I think a coffee filter will do, it's easy to get in alot of stores, but let NurdRage confirme that =)

I wonder how many people bought or are still buying that contaminated MnO2 and getting angry because their reactions are not giving the products they expected... (i mean home chemists =) )

Again, thanks for sharing. NurdRage FTW muhahah

[DOVUSOPERIOR]

whoaaa so simply ? I doesn't need much work it just need the right way!

[sciencoking]

I would rather like to get manganese metal from it for my element collection. How could I do that without having it turn back into MnO2?

[Sillybillydilly]

@sciencoking electrolyzing a solution of MnSO4 in water is most likely the easiest way to do it at home. You'd probably want another piece of Mn wire to start as a seed, and might need a week or so of electrolysis at 1 amp current near 1.5 volts to get a significant amount. Now I think of it, an aluminum plate with one side taped for later preferntial acid dissolution may be another idea for a cathode.

[sciencoking]

i thought about that too, just with MnCl2, but that shouldn´t make that much of a difference (get angry if i´m wrong). What i worry about most is that the Mn might react with the water :/

[NurdRage]

@sciencoking

hmmm... i'll see what i can do.

[sciencoking]

wow, thanks a lot!

[invis648]

Nurdrage, I have a request -- if you get some free time and are bored, would you make a lab cleanup video? How you clean up after doing some of these actions and experiments, and maybe some good safety precautions around the lab after your work is done? Thanks! Great vids!

[freakin1random]

aHA! now i know what that really orange shit is when i try to make Fe2O3. its hydroxide! yay for me. Thank you. (btw, I've found a lot of my solutions growing mold, mainly acetate salts(yes i learned later that they are buffers). im pretty sure that wont be a problem here, but who knows, maybe theres a Mn loving-flesh eating parasite out there :D That'd be pretty cool!)

[sciencoking]

oh, you know that problem?

i always get mold on my potassium hexacyanoferrate solutions o0

[rbmc3]

Awesome video! Keep it up!

[eonomen]

are you going to be doing another sub for science at all?

[Pyroflea53]

@randomenginestuff Coffee filters work just fine. There shouldn't be a substantial difference between them and paper towel.

[Khang112]

Nurdrage.....YOU"RE AWESOME!!!!@!@!@!@!!

[weggles]

It looks like you're using plain brown paper towel. Couldn't that potentially contaminate the product? Or nothing significantly?

[NurdRage]

@weggles

it does, but i wanted to with a "homemade" video.

If you have filter paper go for it :)

[kaninen25]

Is it smarter to use a coffee filter for this, or can that also contaminate it?

[zprime666]

does a coffee filter work?

[rampagetv]

Great video man, but I still don't get why your voice is warped... Im gonna run it through Logic Pro and see what your real voice sounds like...

[Gabbos]

well done

[brainsenburn]

new vid yay

[Khalastas]

1st

[Thtyler]

lol
