Question

derive Henderson equation to calculate ph of buffer solution.​

Answer 1

Answer:

How do you calculate the pH of a buffer solution? You can calculate the pH of buffer solution in two ways. First, you can use the acid dissociation constant expression, and second you can use the Henderson-Hasselbalch equation.

Explanation:

The Henderson-Hasselbalch approximation allows us one method to approximate the pH of a buffer solution. The basic equation is as follows: pH ≈ pKa + log10[A −] [HA] We have straightforward calculations for strong acids and bases, but the computations behind buffers are rather complex and time consuming.
