Hi there,
When electric current is passed through water , it decomposes to givehydrogen gas and oxygen gas. II) Thevolume of hydrogen gas collected at cathode is more than volume of oxygen gas at anode because water is made up of 2 parts of hydrogen and 1 part of oxygen by volume..

Answer:
In water, OXYGEN : HYDROGEN =: 1 : 2
Explanation:
Water consist of two parts of hydrogen and one part of oxygen. That is why in electrolysis of water, volume of gas collected over one electrode is double that of gas collected over the other electrode. electrode with greater volume consists hydrogen whereas electrode with lesser volume consists oxygen.
