Chapter 16, Problem 16E

Interpretation Introduction

Interpretation:

The pH of the given solutions is to be calculated by the suitable method.

Concept introduction: The Henderson-Hasselbalch formula provides an expression by which the pH of a buffer solution can be calculated.

To determine: The pH of the solutions, $150\text{ml}$ of $0.25\text{M}$

$\text{HF}$ with $225\text{ml}$ of $0.30\text{M}$

$\text{NaF}$ , $175\text{ml}$ of $0.10\text{M}$

${\text{C}}_2{\text{H}}_5{\text{NH}}_2$ with $275\text{ml}$ of $0.20\text{M}$

  ${\text{C}}_2{\text{H}}_5{\text{NH}}_3\text{Cl}$ by any suitable method.
