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
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…
nurd word
@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.
i only understood the litmus paper part because we did this in science class earlier this year <3
Tumbs up if you understand nothing.
Anyways nice vis:P
@ericon52168 oh ok, thank you.
@shawnchen018 most data was shown in 25degC
when it’s 20degC ph7 will become ph7.01
there sohuld bve a list somewhere
technically yes….. but safety and liability would be an issue
@NurdRage again you should be a teacher
can you tell us from witch seller you got this ph meter?
Great video!
wgy 7.01 recalabration?
thanks, nurd. I have a meter that’ll read to 0.001, but I didn’t realize it needs storing in salt, so I’ll have to do that. one point you could make is that, if your probe won’t read correctly in different buffers, you can set it to the pH that’s closest to your pH of interest, and that way you’ll know you get the important reading more correct.
nosebleed
lol i am doind this cauase i have end of year exam tomorrow and i am revising cause the exam decides my GCSE groups i wanna get top group again i have been top twise. wish me luck
Are you a T. A. at UTM by any chance?
@NurdRage After finishing first year chemistry at U of T, I couldn’t agree more with that comment.
@NurdRage I can’t belive you would say that it’s 99% boring. I like the experiments but the theory is very interesting aswell.
