Question

what is formed when Hydrochloric acid is added to zinc carbonate then to lime water ?

Answer 1

Answer:

A small amount of hydrochloric acid is carefully poured into the remaining test tube. A small amount of sodium carbonate is added to the acid, and the tube is sealed with a rubber stopper. The two tubes are connected. As a result of the acid-carbonate reaction, carbon dioxide is produced and the lime water turns milky.
