Question

in electrolysis of water why is the volume of gas collected over one electrode double that of gas collected over the other electrode

Answer 1

Heya!!Here is your answer friend ⤵⤵

➡In the process of electrolysis of water , the constituents separate out

The reaction taking place is as follows -

2H2O-----------------------2H2. +. O2.
( on passing
Electricity )

↗It is observed that the volume of gases collected over one electrode is double the gas collected over the other one .

This is due to the fact that hydrogen and oxygen always combines in the ratio 2:1

That is two molecules of hydrogen always combines with one molecule of oxygen to form water .


Hope it helps you ✌✌

Answer 2

In electrolysis of water H2 and O2 are liberated. Volume of H2 gas is double of the volume of O2 gas liberated because one molecule of water contains two atoms of H whereas only one atom of O. Thus, amount of H released is double of that of O.
