Calcium Carbonate and Hydrochloric Acid Reaction

Calcium carbonate is not soluble in water and exists as white precipitate in the water. When aqueous hydrochloric acid is added, calcium chloride, carbon dioxide and water are formed. Calcium chloride (CaCl 2) is soluble in water and colorless. So, it exists as an aqueous solution.

Calcium carbonate - Wikipedia

Alternatively, calcium carbonate is prepared from calcium oxide. Water is added to give calcium hydroxide then carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate (PCC): CaO + H 2 O → Ca (OH) 2 Ca (OH) 2 + CO 2 → CaCO 3 ↓ + H 2 O
