in the oceans, aqueous calcium ion combines 1:1 with aqueous carbonate ion to yield limestone, a solid. What is the expression for the Law of Mass Action for the reverse reaction, the dissolution of calcium carbonate into calcium and carbonate ions? The equilibrium constant for the dissolution of a solid is referred to as Ksp. Ksp = limestone/[calcium][carbonate] Ksp = [calcium][carbonate]/limestone Ksp = [calcium][carbonate] Ksp = [calcium]2[carbonate]/limestone
