Question

When electric current is passed through acidulated water.​

Answer 1

Water decomposes into hydrogen and oxygen on passing electric current through acidulated water. Therefore, it is a decomposition reaction.

Step-by-step explanation:

When an electric current is passed through acidulated water, it will produce a reaction called electrolysis. If an electric current is passed through acidified water, then bubbles of oxygen gas(O2) and hydrogen(H2) gas are produced at the two electrodes immersed in it.

Answer 2

`\bold{\boxed{\huge{\blue{\underline{Answer }}}}}`

When electric current is passed through acidulated water , then it split into hydrogen and oxygen molecule that is H2 and O2

Chemical equation for above reaction :-

2H20 on electrolysis given 2H2 + O2

This spilliting of water due to electricity is called electrolysis .

In electrolysis, H2 moves towards cathode as it forms positive ions whereas O2 moves towards anode as it forms negative ions .
