Chapter 15, Problem 24E

Interpretation Introduction

Interpretation:

The concentrations of ${\text{H}}_{\text{3}}{\text{O}}^{+}$ to the correct number of significant figures, in a solution with each given $\text{pH}$ are to be calculated. The relationship between the number of digits to the right of the decimal places in $\text{pH}$ and the number significant figures in concentration is to be stated.

Concept introduction: The $\text{pH}$ value determines the solution is acidic, basic and neutral in nature.

The $\text{pH}$ value of the given solution is calculated by the formula,

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

To determine: The concentrations of ${\text{H}}_{\text{3}}{\text{O}}^{+}$ to the correct number of significant figures, in a solution with each given $\text{pH}$ and the relationship between the number of digits to the right of the decimal places in $\text{pH}$ and the number significant figures in the concentration.
