Chapter 15, Problem 15.70SP

Interpretation Introduction

Interpretation:

The volume ratio of ${\text{NH}}_{\text{4}}\text{Cl}$ and ${\text{NH}}_3$ in $\text{9}\text{.80}\text{pH}$ buffer solution should be calculated.

Concept Introduction:

Henderson–Hassel Balch Equation:

The $\text{pH}$ of the given buffer solution is given by Henderson–Hassel Balch Equation it is,

$\text{pH}{\text{=pK}}_{\text{a}}\text{+}\text{log}\frac{\text{[base]}}{\text{[acid]}}$

Buffer solution:

The equal concentrations of mixture of conjugate acid-base solutions is known as buffer solution.

The buffer solution has a constant $\text{pH}$ because of common ion effect.
