Chapter 17, Problem 45A

Interpretation Introduction

Interpretation:

The dissolution of the ionic solute in water represents an equilibrium process; the reason behind this fact is to be explained.

Concept Introduction :

The equation in which the number of atoms on reactants’ side is equal to the number of atoms on the product side, this reaction is said to be a balanced chemical equation and the state where the rate of reaction of forwarding and reverse reaction becomes equal to each other, is known as an equilibrium state.

Answer to Problem 45A

The dissolution of ionic solute in water is an equilibrium process because there are two opposing processes, such as the dissolution and the crystallization, are going in two different directions for a reaction. So this is the reason for this reaction the dissolution of an ionic solute and water.

Explanation of Solution

The solubility of the ionic solute depends on its solubility product. An ionic solute is not completely dissolved in water while it is partially dissolved and partially remains the solution. Solubility is the dissolving ability of the substance while the solubility product constant represents the equilibrium between the substance and its ions dissolved in the solution. Its value depends on the amount to which the compound can dissolve in the water.

Conclusion

The ionic solute is partially dissolved in the solution.
