Chapter 17, Problem 3CR

Interpretation Introduction

Interpretation:

The affinity of the acetate ion for the protons is to be compared with the affinity of water molecules for protons on the basis of the given statement. An explanation for the given fact that the basic solution is produced if sodium acetate is dissolved in water is to be stated. The equilibrium reaction equation for the ionization of acetic acid in water and the reaction of the acetate ion with water in a solution of sodium acetate is to be identified.

Concept Introduction:

In a chemical equilibrium the concentration of the reactants and products remain constant. The rate of the forward reaction is equal to the rate of backward reaction. The affinity measures the interaction between the molecules. Acetic acid is a weak base due to which dissociates partially in water. Therefore, acetic acid shows poor affinity than water.
