Answer:
An acid , such as dilute hydrochloric acid, is added to the test compound. Carbon dioxide gas bubbles if carbonate ions are present. Limewater is used to confirm that the gas is carbon dioxide.
Explanation:
metal carbonate + hydrochloric acid → metal chloride + water + carbon dioxide
metal carbonate + nitric acid → metal nitrate + water + carbon dioxide
metal carbonate + sulphuric acid → metal sulphate + water + carbon dioxide
