What is the common ion effect in a dissociation equilibrium?

Options

  1. AIt shifts the equilibrium toward the dissociation of the substance.
  2. BIt has no effect on the equilibrium.
  3. CIt shifts the equilibrium away from the dissociation of the substance.
  4. DIt causes the equilibrium to reverse.

Correct answer

A. It shifts the equilibrium toward the dissociation of the substance.

Step-by-step solution

The common ion effect is a phenomenon where adding a substance that provides more of an ionic species already present in the dissociation equilibrium shifts the equilibrium toward the dissociation of the substance, reducing the concentration of hydrogen ions in this case.
