Homework Help: Chemistry- Buffers

Posted by Mikey on Sunday, December 5, 2010 at 9:53pm.

a buffer is prepared by mixing .208 L of 0.452 M HCl and 0.5 L of 0.4 M sodium acetate. When the Ka= 1.8 x 10^-5

I figured out that the pH= 4.74

but then it asks how many grams of KOH must be added to the buffer to change the pH by .155 units?
