Lab Equipment: pH measurement with paper and meters [Part 1]

In this video we briefly discuss ways of measuring pH using pH paper and a meter.

Omega engineering sells a variety of pH meters and related equipment and will also sell to individuals: http://www.omega.com

You should be a Chemistry teacher.

I mean, you are gonna be the coolest Chemistry teacher ever.

All the students are gonna love you :D

I mean, much better than my Chemistry teachers anyway.

They just read from the textbook and tell us to copy them down..

@ZyGaming While the approach of a chemistry teacher depends on the teacher, the subject itself is 99% boring with only 1% cool stuff. I might look cool on youtube because i show mostly the 1% cool stuff. But to get to that 1%, you have to first slog through the 99%

Is your teacher *actually* boring? or is the stuff they're teaching boring? ;)

Is there is any type of acid, etc. that would be able to completely dissolve a vegetable plant upon contact, or within say a matter of minutes?

A client of my landscaping company wants to have a large container filled with a substance that she can throw her unwanted vegetable plants, leaves, etc. into and have them completely dissolve in the shortest amount of time possible, preferably on contact. Any advice, or suggestions would be greatly appreciated.

Thank you.

@martha2ful technically yes..... but safety and liability would be an issue, any substance that powerful would also dissolve human flesh very effectively. Even a small splash out when you drop something would be a horrific.

I recommend just a mulcher or similar mechanical approach to grind the matter into a paste and then flush it or compost it.

algebra, finally something in one of these videos i understand

@martha2ful That sounds sketchy...

Urgh. Calibration.

@ZyGaming man, it's a 99% boring one(this vid). but it's great to watch

[INYO121277]

hey a joke :

how to defferentiate acid pH from alkalic ones

drink it.

if tastes sour, that's its acid, if tastes bitter : alakalic

put your finger in it

burns : low pH

sticky : high pH

liabilities : death, scar, and a trip to hospital

@NurdRage

I came here from your fluorescence thermochromism video (which was totally awesome btw) cause you said it would probably bore us out of our minds...in fact I find this most informative...i'm not sure what I would actually put this into practice with but still...none the less...very informative...I have measured PH before but only for watering specific plants and stuff that prefer certain PH levels...haha...

@46564364 the glass electrode probably died, get a new one.

Hey Nurdrage, I own a pH meter, but yesterday I immersed it on a 60% nitric acid solution and it doesn't read the pH anymore, what happened? Thank you.
