Chapter 16.4, Problem 16.4.2SR

Interpretation Introduction

Interpretation:

The ${\text{[H}}^{\text{+}}\text{]}$ in a given solution with pH is 5.75 has to be determined.

Concept Information:

pH definition:

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

The $\text{pH}$ of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

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

On rearranging, the concentration of hydrogen ion ${\text{[H}}^{+}\text{]}$ can be calculated using pH as follows,

${\text{[H}}^{+}\text{]}\text{=}{\text{10}}^{\text{-pH}}$

To Determine: The ${\text{[H}}^{\text{+}}\text{]}$ in a given solution with pH=5.75
