Synthesis of Calcium Chloride
Accepted Answer
Calcium chloride can be synthesized by the reaction of calcium carbonate with hydrochloric acid:
$CaCO_3 + 2HCl → CaCl_2 + CO_2 + H_2O$
This reaction can be carried out in a variety of ways, including:
1. Direct reaction of calcium carbonate with hydrochloric acid: This is the most straightforward method, and it can be carried out by adding calcium carbonate powder to a solution of hydrochloric acid. The reaction will produce calcium chloride, carbon dioxide gas, and water.
2. Dissolution of calcium oxide in hydrochloric acid: Calcium oxide can be dissolved in hydrochloric acid to produce calcium chloride and water. This reaction is typically carried out by adding calcium oxide powder to a solution of hydrochloric acid.
3. Reaction of calcium hydroxide with hydrochloric acid: Calcium hydroxide can be dissolved in hydrochloric acid to produce calcium chloride and water. This reaction is typically carried out by adding calcium hydroxide powder to a solution of hydrochloric acid.
Once the reaction is complete, the calcium chloride can be isolated from the reaction mixture by filtration or evaporation.
