The extent of ionization of a weak electrolyte is increased by adding to the solution a strong electrolyte that has an ion in common with the weak electrolyte.

Question

Quizplus · Accepted Answer

Adding a strong electrolyte with a common ion to a solution of a weak electrolyte actually decreases the extent of ionization of the weak electrolyte due to the common ion effect, which shifts the equilibrium towards the un-ionized form of the weak electrolyte.
