Hello, I do apologize DrBob222 I didn't see your post from yesterday. However, thank you for help and thank you devron for your help as well. The extra credit only says how would prepare a .6m acetate buffer with a pH = 4.0. So I too, wasn't sure what the question was ...

How to start these problems out: Please help thank you Use the Henderson-Hasselbach equation: pH = pKa + log [A-]/[AH], where A- is the conjugate base and AH is the weak acid. Calculate the pH of an acetate buffer in which the acetate concentration [CH3COO-] is 3.5 times great...
