Explanation:
Electrolysis is the process of using an electrical current to separate water into hydrogen and oxygen gas.hydrogen is collected at cathode and oxygen is collected at anode.if you want to verify follow the process
To test for hydrogen gas evolved, insert a lighted splint into the test tube. The lighted splint should extinguish with a characteristic "pop" sound.
to test for Oxygen, oxygen supports combustion. so,a good method of testing for oxygen is to take a glowing splint and place it in a sample of gas, if it re-ignites the gas is oxygen
