WebAnswer: This is actually a buffer type question: There are problems with what you have submitted: You have 0.05M NaCH3COO. ( NOT 0.05M NaCH3COOH) What is the molarity of the CH3COOH? If both of these have molar concentration 0.05M , then the solution is simple: If [CH3COOH] = [NaCH3COO] The... WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.
