Question

The Henderson-Hasselbalch equation is used toQuestion 2 options:A) estimate the pH of a buffer solution.B) calculate dissociation constants.C) calculate reduction potential.D) estimate voltaic potential.

Answer 1

Answer

A. estimate the pH of a buffer solution.

Explanation

The Henderson–Hasselbalch equation can be used to calculate the amount of acid and conjugate base to be combined for the preparation of a buffer solution having a particular pH, as shown below.

$pH=pKa+\log_.\frac{[A^-]}{[HA]}$

Therefore, the Henderson–Hasselbalch equation can be used to estimate the pH of a buffer solution by approximating the actual concentration ratio as the ratio of the analytical concentrations of the acid and of salt.

The correct answer is: option A. estimate the pH of a buffer solution.
