Chapter 14.7, Problem 14.9PSP

(a)

Interpretation Introduction

Interpretation:

$pH$ value of a $0.015M$ solution of hydrazoic acid should be calculated.

Concept Introduction:

The concentration of hydrogen ion is measured using $\text{pH}$ scale.  The acidity of aqueous solution is expressed by $\text{pH}$ scale.

For calculation of pH, the following formula is used,

  $\text{pH}\text{=}-\log {\text{[H}}^{\text{+}}\text{]}$

If the value of $\text{pH}$ is less than $7$, then the solution is acidic whereas if the value of $\text{pH}$ is greater than $7$, then the solution is basic.

(b)

Interpretation Introduction

Interpretation:

Percent ionization of hydrazoic acid should be calculated.
