Homework Help: Chemistry

Posted by Hannah on Tuesday, April 10, 2012 at 10:43am.

You have 250mL of a 0.56M solution of sodium acetate. How many mL of 0.50M acetic acid should be added to make a buffer of pH 4.40?

I think this is a buffer system so I would use pH=pka + log base/acid

so would I set this up as
4.40 = 4.74 + log base/ 1.8e-5 from acetic acid?
