Answer:

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<em><u> 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.</u></em>
