Answer:

1. The percent ionization in the potassium formate solution is smaller than that in pure water because of the common ion effect.

2. The equilibrium for the dissociation of formic acid is shifted to the left by this addition, and a smaller amount of acid dissociates.

Explanation:

The common ion effect refers to the effect on equilibrium that is observed when an ion that is already contained in the solution (common ion) is added to a solution. The addition of a common generally results in a shift in equilibrium positiont towards the removal of the common ion from solution. This is according to Le Châtelier's Principle which states that if an equilibrium becomes unbalanced, the reaction will shift to restore the balance.

The common ion effect decreases the ionization of a weak acid as the addition of more of an ion that is a product of this equilibrium will shift equilibrium towards removal of the ion.

Adding a common ion also decreases solubility, as the reaction shifts toward the left in order to annul the constraint of the excess ion in the product side of equilibrium.

The percent ionization in the potassium formate solution is smaller than that in pure water because of the Common ion effect. The equilibrium for the dissociation of formic acid is shifted to the left by this addition, and a smaller amount of acid dissociates.

What is Equilibrium law?

Equilibrium law states that if any external effect is applied on the equilibrium state of any chemical reaction, then the equilibrium will shift towards that side where the effect will decrease.

Common ion effect occurs when the already present ion in the solution is further added to the solution which increases the concentration of that ion in the solution and equilibrium will shift towards the side where common ion effect will decreases.

That's why the percentage of ionization in the potassium formate solution is less than the percentage of ionization in pure water. And due to common ion effect equilibrium will shift towards the left side where dissociation decreases and the concentration of ions is also decreases.

Hence correct options are smaller, common ion effect, left and smaller.
