Homework Help: Chemistry

Posted by Alex on Thursday, March 4, 2010 at 3:01pm.

I have a 1L solution of 0.02M sodium acetate and 0.02M acetic acid. What is the pH after the addition of 0.05 moles of hydrochloric acid?

I know this is a buffer question but I have no idea how I am supposed to go about getting the answer... I know Ka values for acetic acid, but I still can't get anywhere.
