A
Calculating the pH of a Buffer: pH = pk + log HA This equation is known as
the Henderson-Hasselbalch equation. This applies only to buffers.

Expert Solution
Step 1: Defining buffer solution

Answer:

Buffer solution is a type of solution that resists the change in its pH on adding small quantity of acid or base. Solution of weak acid (CH3COOH) and its conjugate base (CH3COO-) can act like a buffer solution.
