Chapter 15, Problem 16E

Interpretation Introduction

Interpretation:

The ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ion concentration for the each of the given aqueous solution at $\text{25}\text{°C}$ is to be calculated and the solution is to be classified as acidic or basic.

Concept introduction: The water auto ionization constant is denoted by $K_{\text{w}}$ .

The concentration of ${\text{H}}_{\text{3}}{\text{O}}^{+}$ and ${\text{OH}}^{-}$ is calculated by the formula,

$\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]\left[{\text{OH}}^{-}\right]=K_{\text{w}}=1.0\times {10}^{-14}$

To determine: The ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ion concentration for the given solutions at $\text{25}\text{°C}$ and the classification of each solution as acidic or basic.
