Equations To Remember

Question 1

What formula do you use if you need to find the pH and are given the [OH]?

Answer 1

1) pOH = -log [?]

2) pH = 14 - pOH

Question 2

How to calculate molar mass?

Answer 2

Add the atomic numbers and multiply any subscripts

Question 3

What are the steps and equations you should use if you need to find [H] and are given the pH?

Answer 3

1) pH = -log [H+]
2) Substitute given pH
3) multiply both sides by -1 to remove the -log
4) use log = 1 x 10^x and sub both sides in for x
5) 1 x 10 and log cancel out
6) [H+] = answer
