the Henderson-Hasselbalch equation. This applies only to buffers.
1. What is the pH of a buffer that is 0.12 M in lactic acid, CH₂CH(OH) COOH, and
0.10 M in sodium lactate? K₁ =1.4×10¹.

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.
