HOw many ml of 0.120M KOH must be added to 60ml of 0.2M HF to produce a solution with a pH of 3.3? (pKa of HF is 3.3)

Ans: 5ml

- THe answer key shows that c1v1 = c2v2 eqn can be used.

- When I first approach this question, I quickly use the pH to find out how much [H+] is needed.

Please help! Thanks in advance!
