Chapter 15, Problem 64A

Interpretation Introduction

Interpretation: The reason for ions to become solvated in an aqueous solution needs to be explained.

Concept Introduction: Solvation is a process by which an ion gets surrounded by solvent molecules or ions.

Explanation of Solution

In an aqueous solution, the solvent is liquid water. Here, water has two parts, hydrogen ion has a partial positive charge and hydroxide ion has a partial negative charge. An ion can be positive or negative. Now, the positive ion gets surrounded by negatively charged hydroxide ions and the negative ion gets surrounded by a positive hydrogen ion. Thus, the reason for ions to become solvated in an aqueous solution is the partial positive and negative charge on the water molecule.
