1.	On passing electricity through acidulated water, the gaseous products obtained are collected in two separate test tubes A and B. The volume of the gas collected in test tube A is double the volume of gas collected in test tube B. Identify the two gases in test tubes A and B respectively.
Answer» Hydrogen and OXYGEN Oxygen and hydrogen Hydrogen peroxide and oxygen Oxygen and water vapour Solution :On passing ELECTRICITY through ACIDULATED water it DECOMPOSES to hydrogebn and oxygen. Volume of hydrogen evolved in test tube A is double the volume of oxygen COLLECTED in test tube B.
