Finding pH and pOH using MOLARITY of a solution | Chemistry with Cat

[@gloryifeany7840]

You really explained this basic concepts very well.i would rate you 100%.

[@torresthemonster]

If I had you as my teacher, I wouldn’t miss one day and get 100 on every exam.

[@fatmanlover962]

real

[@fatmanlover962]

we can only dream

[@viplavsinghal2005]

Also I might be wrong but when you did -log[.0725] in the last problem, you should have gotten 1.1397 instead of .1397 which would change the final answer.

[@Moony-y7i]

Agreed

[@journeywithrahat]

She speaks so calm

[@sachitsharma1661]

Suddenly i realized i love chemistry

[@rainsmush]

This helped me sooo much THANKS CAT!!
love how its simple clear and to the point thankyou!!!
"new sub":)
pls keep making videos and you are wayy to underrated

[@dkstudio702]

if she was my high school teacher my attendance is 100%

[@RobinBaral52]

Shouldn't there be two minuses in SO4? 1:37

[@aryanshinde-student19777]

Yes

[@maxzytaruk8558]

this was so incredibly well explained! Thanks! :)

[@Jamalashwah]

Hello
The last question:
c=n/v
c= 0,029 mol / 0,4 L
c= 0,0725 mol/L
pOH = -log (0,0725 M)
pOH= 1,139
14 - 1,139
pH = 12,86
THX YOU

[@greatorg9498]

YOU ARE MARVELOUS and so nice how you explain in order, step by step...
Thank you so much for your video !

[@vivekj-ki5cq]

im a grduate in chemistry and i donno why am i watching this but that feels good... and btw great explaination

[@axeldaliramirezgonzalez1830]

Thank you , that was a very useful explanation that saves me from reading 20 pages :)

[@vijayadithya492]

Very great explanation. My concepts are clear. thank you madam. Big Fan.

[@تيسيرخان-ق8ج]

You are the best and thank you very much

[@rabishkumar1592]

In last question
POH=1.139
PH=12.86

[@victorngare4304]

True

[@CC-rh1in]

what if we need the pH of Ca(OH)2?

[@viplavsinghal2005]

So for example lets say the molarity of Ca(OH)2 is .01M. We would first do -log [.02] because there are 2 OH ions, We get around 1.70. Then we would just do 14-1.70 resulting in an answer of 12.30. Sig figs might be off

[@i.2.igamer920]

nice thats helps a lot

[@mahreentoor4086]

Informative

[@joshuanyeuwane]

i love this

[@faithmentee1867]

Thanks

[@chandraguerrero3361]

I’m watching this video because I don’t fully understand the basics. So I really wish you would have written the “base 10” model 🥴 …. Because that’s where you lost me 😔

[@maxzytaruk8558]

oh that just means "multiplied by ten to the power of -POH" as in [OH-] = 10 ^-POH. I hope that helped, I know I'm a year late to your comment though haha

[@gavinkinch1911]

Wish u were my chem teacher

[@iamGauravkumawatt]

Tq🤗

[@16_biplabkumarpradhan66]

Well explain mam

[@valeriaa_ar]

Thanks :)

[@nZkKanra]

is she recording with a landline phone lmao

[@KUROSAKIKUN-dn6gv]

Bro😂😂😂

[@naveelarani7153]

Thanks from Pakistan

[@MechanicalGuy]

Beautiful 😍😍😍😌

[@AliHassan-hb1bn]

You should show without using a calculator.

[@edrianejay7126]

Do you also teach in onlyfans?

[@schmvsmsi3920]
