A buffer with a pH of 4.30 contains 0.25 M of sodium benzoate and 0.20 M of benzoic acid. What is the concentration of [H ] in the solution after the addition of 0.052 mol of HCl to a final volume of 1.5 L?
I know that Ka = 6.3x10-5
do I need to use an ice table or is the pH=pKa+log(A/HA) enough?

You need to use an ICE chart. Post what you can and explain what you don't understand and I can help you through it if you get stuck.
