Question

Why is the amount of gas collected in one of the test tubes in activity 1.7 double of the amount collected in the other? Name this gas.

Answer 1

Answer:

Explanation: because water molecule is H20

So that means for every oxygen atom theres 2 hydrogen atoms .i.e, the ratio of H:O is 2: 1. So when current is passed through the electrodes the gas at each electrodes is the the same ratio which is why at the cathode theres more gas (h2) which is twice of that of AT the anode

Answer 2

$<bullet> Water contains two parts of hydrogen and one part oxygen. Therefore, during the electrolysis of water the amount of hydrogen gas collected in one of the test tubes is double than that of the oxygen produced and collected in the other test tube.$
