Answer 2

Answer:

The amount of gas collected in cathode is twice that of at anode. The gas collected at cathode is hydrogen while the gas collected at anode is oxygen. Since the hydrogen and oxygen combine in the ration 2: 1 to form a water molecule, the amount of hydrogen gas is double that of oxygen.May 18, 2015
