Question

Name the gas released when acid reacts with
metallic carbonate write the chemical Equation
of the reaction when this gas is passed though
time water what is the colour of precipitate
obtained in this reaction?
​

Answer 1

Explanation:

Carbon dioxide gas is liberated when dilute hydrochloric acid reacts with sodium hydrogen carbonate. When the gas liberated in the reaction is passed through lime water, lime water turns milky or a white precipitate of calcium carbonate is formed.

Answer 2

Explanation:

when acid reacts with metal carbonate it release carbon dioxide gas (CO2)

Acid +metal carbonate= salt + water + carbon dioxide

• when the gas passed through lime water it turns milky and white colour precipitate calcium carbonate is formed
