1.	. In the electrolysis of water0) Name the gas collected at anode and(Ăź) Why is the volume of gas collected at one(ili) What would happen, if dil H,SO, is notcathode.electrode double than the other?added to water?
Answer» (a)gas is collected at the cathode andgas is at anode. (b) The gas which is collected in double the amount in the electrolysis of water experiment is hydrogen. This is becausecontains 2 parts of hydrogen element and 1 part of oxygen element by volume. (c) Hydrogen gas burns with a pop sound when the burning splinter is brought near the gas. If a smoulding match stick is brought in contact with oxygen gas, it starts burning brightly. gas collected at cathode is hydrogen and gas collected at anode is oxygen pure water is a bad conducted of electricity.By aading a few drops of sulphuric acid,we make it a good conductor of electricity.

gas collected at cathode is hydrogen and gas collected at anode is oxygen

pure water is a bad conducted of electricity.By aading a few drops of sulphuric acid,we make it a good conductor of electricity.
