Question

. In the electrolysis of water (i ) name the gas collected at the cathode and. 2 anode (ii) write down the ratio between hydrogen and oxygen​

Answer 1

Explanation:

Electrolysis of water is actually the decomposition of water with the help of electric current.

Now, during electrolysis of water, the gas collected at cathode is hydrogen gas whereas the gas collected at anode is oxygen.

Secondly, the ratio between amounts of hydrogen and oxygen gas collected is 2:1 ( because the reaction goes on like

2H2O------> 2H2 + O2)

Hope it helps!
