Question

There exist an equilibrium between solid BaSO₄, Ba²⁺ and SO₄²⁻ ions in aqueous medium. Now, if equilibrium is disturbed by the addition of

(I) BaNO₃ and

(II) K₂SO₄ in different experiments and the equilibrium is re-achieved, then match the columns given below. (Thick line represents the initial equilibrium and the dotted line represents the approach of system towards equilibrium).
