Finding pH and pOH using MOLARITY of a solution | Chemistry with Cat
When we're given pH or pOH in a question, we can easily calculate the concentration of hydrogen ions or hydroxide ions, and then with that we can calculate the molarity of a solution! This is classic chemistry test and exam gold, so make sure you can do that AND relate pH and pOH. Remember pH + pOH = 14!
Practice problems and answers can be found on the Chemistry with Cat Instagram: / chemwithcat

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.

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

what if we need the pH of Ca(OH)2?
@viplavsinghal2005
@viplavsinghal2005 2 года назад
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’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
@maxzytaruk8558 Год назад
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
