What is the reaction of a small amount of limestone with dilute hydrochloric acid

Answer:

The reaction of a small amount of limestone with dilute hydrochloric acid is:A large number of bubbles are produced, white precipitate disappears, and there is a pungent odor (hydrogen chloride)Because dilute hydrochloric acid reacts with limestone to produce carbon dioxide, water and calcium chloride, so there will be a bubble, calcium carbonate is consumed regret to disappear, so the white precipitate disappeared. In the heating conditions, dilute hydrochloric acid volatile volatile, so there will be a pungent odor
Room temperature reaction phenomenon: the white precipitate gradually disappear, and produce a large number of bubbles, and accompanied by a large heat release. The gas can make clear limewater cloudy, because it is a dilute hydrochloric acid, pungent odor is not obvious.

The main component of limestone is calcium carbonate.Calcium carbonate reacts with dilute hydrochloric acid to produce calcium chloride and carbonic acid, which is unstable and easily decomposed into carbon dioxide and water. So calcium carbonate reacts with dilute hydrochloric acid to produce calcium chloride, carbon dioxide and water.The chemical formula CaCO3 + 2HCl==CaCl2 + CO2 = H2O +
