What is the common ion effect a result of?

Options

  1. AAddition of a different ion
  2. BRemoval of an ion
  3. CAddition of an ionic species already present in the equilibrium
  4. DA change in temperature

Correct answer

C. Addition of an ionic species already present in the equilibrium

Step-by-step solution

The common ion effect occurs as a result of adding an ionic species that is already present in the dissociation equilibrium, causing the equilibrium to shift in the direction of reduced ionization or dissociation.
