Chapter 16, Problem 16.95QE

Interpretation Introduction

Interpretation:

The concentration of ammonium ion in a $pH9.00$ solution that forms when concentrated $NaOH$ is added to $0.100MN{H}_{4}Cl$ has to be calculated.

Concept Introduction:

The $pH$ of a buffer solution can be calculated by using Henderson – Hasselbalch equation.

  $pH=p{K}_a+\log \frac{C_b}{C_a}$

Where, $C_b$ is the concentration of base and $C_a$ is the concentration of acid.
