Chapter 10.13, Problem 1QQ

Interpretation Introduction

Interpretation:

According to Henderson–Hasselbalch equation, among the given options, which quantities is not present acid has to be identified.

Concept Introduction:

The relationship between $p{K}_a$ and $pH$ for buffer solutions in which the conjugate

Acid–base pair concentration ratio is something other than 1-to-1 is given by the

Equation.

  $pH=p{K}_a+\log \frac{[A^{-}]}{[HA]}$

This equation is called the Henderson–Hasselbalch equation.
