Karsyn Phillips · Answer 1

CaCO3 (aq) → Ca2 + (aq) + CO3 2 - (aq)

Explanation:

Dissolution reactions are reactions that occur when a solute either in gaseous, liquid, or solid form dissolves in a solvent such as water to form a solution. In this case we are given Calcium carbonate (CaCO3) which undergoes dissolution according to the equation; CaCO3 (aq) → Ca2 + (aq) + CO3 2 - (aq) Then the bicarbonate ion combines with two protons from water to form a weak acid H2CO3. The weak acid is then broken down to form CO2 and H2O since its unstable.
