Chapter 16, Problem 7E

Interpretation Introduction

Interpretation:

The $\text{pH}$ value for the given $\text{0}\text{.15}\text{M}$$\text{HF}$ solution, $\text{0}\text{.15}\text{M}$$\text{NaF}$ solution and mixture of $\text{0}\text{.15}\text{M}$$\text{HF}$ with $\text{0}\text{.15}\text{M}$$\text{NaF}$ is to be calculated.

Concept introduction: The $\text{pH}$ value determines if a given solution is acidic, basic or neutral in nature.
The $\text{pH}$ value of the given solution is calculated by the formula,

$\text{pH}=-\log \left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$

To determine: The $\text{pH}$ value for the given $\text{0}\text{.15}\text{M}$$\text{HF}$ solution, $\text{0}\text{.15}\text{M}$$\text{NaF}$ solution and mixture of $\text{0}\text{.15}\text{M}$$\text{HF}$ with $\text{0}\text{.15}\text{M}$$\text{NaF}$ .
