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!

Cat has a BMSc and MSc. SHE HAS BEEN IN YOUR SHOES AND STRUGGLED ON THOSE EXAMS! She currently tutors university and high school chemistry, and she's here to help YOU! She creates quick videos that teach you everything you need to know to not only pass chemistry but ace it!

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.

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

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

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 😔
