1.	Name the gas liberated when an acid reacts with metallic carbonate. Write the chemical equation of the reaction when this gas is passed through lime water. What is the colour of the precipitate obtained in this reaction ?
Answer» Solution :When an ACID reacts with metallic CARBONATE , carbon dioxide gas is LIBERATED. When carbon dioxide gas is passed through lime WATER, calcium carbonate is produced as a WHITE precipitate. The chemical equation is : `Ca(OH)_(2)(aq) + CO_(2)(g) rarr CaCO_(3)(s) + H_(2)O`.
