One Liter of Water Is Mixed with Excess Calcium Carbonate,resulting

One liter of water is mixed with excess calcium carbonate,resulting in the equilibrium below. CaCO₃(s) D Ca²⁺(aq) + CO₃^2-(aq)
What is the effect on the solubility of calcium carbonate when aqueous nitric acid is added? (Assume no change in volume.)

A) the solubility of CaCO₃ decreases because the acid increases the amount of CO₃^2-.
B) the solubility of CaCO₃ increases because the acid increases the amount of CO₃^2-.
C) the solubility of CaCO₃ decreases because the acid decreases the amount of CO₃^2-.
D) the solubility of CaCO₃ increases because the acid decreases the amount of CO₃^2-.
E) the solubility of CaCO₃ is unchanged.
