Chapter 19, Problem 14STP

Interpretation Introduction

Interpretation:

The incorrect statement about common ion effect is to be identified.

Concept introduction:

The decrease in solubility of a solute due to addition of another ionic solute having a common ion with the previous one is called common ion effect.

Answer to Problem 14STP

The statement C is not true and is the correct answer.

Explanation of Solution

In common ion effect, due to addition of a solute with common ions, the products formed in the dissociation of the earlier solute increases which will shift the reaction equilibrium towards the non-aqueous products (solid solute reactants) of the system.

Conclusion

All the other options were true with respect to the common ion effect and therefore cannot be the correct answer.
