Why is the volume of gas collected over one electrode double than that of gas collected over the other electrode?

Water is composed of 2 atoms of H and 1 atom of O. Therefore the amount of H is double than that of O. The two electrodes collect H2 and O2 separately, therefore, the volume of gas collected in one electrode is double the volume of gas collected in the other electrode.

Why is the volume of gas collected at the anode larger than expected?

At cathode the volume of the gas (Hydrogen) is double than the volume of gas (Oxygen) at the anode because in each molecule of water (H2O) you can see that there are 2 atoms of hydrogen and 1 atom of oxygen.

Why is the amount of hydrogen gas collected in the electrolysis of water double of the amount of oxygen gas?

The volume of the hydrogen produced is always twice the volume of the oxygen produced, because water contains two atoms of hydrogen for each atom of oxygen.

Which gas is double the other and where is it collected?

Thus, the amount of hydrogen gas collected is always double in amount compared to the oxygen gas collected from electrolysis of water.

When electrolysis of water is done two gases are collected in two tubes why the volume of one gas is double of the amount collected in the other name this gas?

The chemical reaction involved in the electrolysis of water is From the above reaction it is clear that the amount of hydrogen gas and the oxygen gas formed are always in the ratio of 2:1. Therefore the volume of gas collected in the first test tube is double the volume of the gas collected in second test tube.

Which gas is collected more in electrolysis of water?

hydrogen
(b) The gas which is collected in double the amount during the electrolysis of water is hydrogen. This is because water contains two parts of hydrogen element as compared to one part of oxygen element by volume.

Why is the volume of hydrogen gas obtained on electrolysis of water is twice the volume of oxygen gas produced also give the balanced chemical equation for the same?

Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g) The number of hydrogen molecules produced is thus twice the number of oxygen molecules. Assuming equal temperature and pressure for both gases, the produced hydrogen gas has, therefore, twice the volume of the produced oxygen gas.

Why is amount of gas collected?

Its evident from the equation that 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.

Why is the volume of gas collected?

The two electrodes collect H and O separately . We know that hydrogen composition in water is double than oxygen , so we find volume of gas collected in one electrode is double than volume of gas collected in another electrade .

Why in electrolysis of water cathode contains double volume of gas than anode which gas is collected in anode?

ii The gas which is collected in double the amount during the electrolysis of water is hydrogen. This is because water contains two parts of hydrogen element as compared to one part of oxygen element by volume.

Which gas is formed at cathode during electrolysis of water?

hydrogen gas
Electrolysis of water produces hydrogen gas at the cathode, which contains a lower proportion of deuterium than the original water.

Why is the volume of hydrogen gas collected in electrolysis double?

It can be observed from the balanced chemical equation that the volumes of hydrogen and oxygen produced during electrolysis are in the ratio 2:1. Thus, the volume of hydrogen gas collected in the process is double than that of oxygen. Was this answer helpful?

What is the volume of gas collected over one electrode?

The volume of gas collected over one electrode is double than that of the gas collected over the other electrode as the ratio of H : O in water is 2 :1. Please log inor registerto add a comment.

Which gas is collected in the electrolysis of water?

In the electrolysis of water, the gas collected at cathode is hydrogen and the gas collected at anode is oxygen. The gas which is collected in double amount is hydrogen.

What is the volume occupied by hydrogen gas during the reaction?

The reaction is shown as below: As you can see that water splits in to 2 molecules of hydrogen and 1 molecule of oxygen. Since, number of molecules of hydrogen released is double the number of molecules of oxygen released, Volume occupied by hydrogen gas is double the volume occupied by oxygen gas.
