Given the concentration of the conjugate acid and the conjugate base, how do you calculate the pH of a buffer? Since the Henderson-Hasselbalch equation and the Ka expression are the same, either can be used use the Henderson - Hasselbalch equation Use the Ka expression of the conjugate acid to calculate [H*], then calculate pH Use the Kb expression of the conjugate base to calculate [OH-], then calculate pH

Expert Solution
Step 1: Buffer solution:

The solution that resists the change in pH is known as a buffer solution. The buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. It resists the pH changes when a small amount of strong acid or base is added to it.
