When 40 mL of 0.20 M CH3COOH is mixed with 40 mL of 0.20 M CH3COOK, what type of solution is the resulting mixture?

Answer 1

The mixture results in a solution that is a BUFFER. This is because it contains a weak acid (CH3COOH) and the salt of that acid (CH3COOK). This is the definition of a bufer.
