Chapter 14, Problem 14CE

Interpretation Introduction

Interpretation:

Whether the value of $K_{\text{w}}$ increases or decreases above $25°\text{C}$ is to be stated. whether the pH of distilled water at $50°\text{C}$ is greater or less than $7.0$ is to be stated.

Concept introduction:

The $\text{pH}$ of a solution indicates the concentration of hydronium ion in the solution and acidity of the solution. When the concentration of hydronium ion in the solution increases, then the $\text{pH}$ of the solution decreases that is acidity increases. When the concentration of hydronium ion in the solution decreases, then the $\text{pH}$ of the solution increases that is basicity increases.
