A salt 'X' of a metal which is used in the galvanizing process on heating produces an oxide of that metal 'Y' and a gas 'Z' . Z is used in the preparation of soda water, and 'Y' is used as a base of white paint. Identify X, Y, Z.

Text Solution

Verified by Experts

Since Z is used in making soda water, it is carbon because zinc carbonate on heating produces zinc oxide and carbon dioxide. Zinc oxide is used as paint. So, X is zinc carbonate, Y is zinc oxide and Z is carbon dioxide. dioxide. The metal carbonate is zinc carbonat
