Question

what is the reaction of hydrochloric acid with calcium carbonate​

Answer 1

Answer:

Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. 2HCl (aq) + CaCO 3(s) CaCl 2 (aq) + CO 2(g) + H 2 O (l). When Calcium carbonate is not soluble This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions.

Answer 2

Answer:

Calcium carbonate reacts with dilute acids to produce a calcium salt, water and carbon dioxide gas: calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide.
