Chapter 19, Problem 74A

Interpretation Introduction

Interpretation : The kind of salts that hydrolyze water is to be explained.

Concept Introduction : One of the products of a neutralization reaction is salt. Salt constitutes a cation from a base and an anion from an acid. They are neutral in solution form.

Answer to Problem 74A

Salts that formed from the strong acid and weak base or the strong base and weak acids hydrolyze water.

Explanation of Solution

When salt is dissociated, its cations or anions either remove hydrogen ions or give hydrogen ions to water.

Positive ions in salts that form acidic solutions cause them to release hydrogen ions into the water.

Negative ions in salts that create basic solutions draw hydrogen ions from water.

Salts are created when a weak acid and a strong base, or a weak base and a strong acid are said to be hydrolyzed.
