Question

what type of reaction takes place when an electric current is passed through water

Answer 1

Hey dear !!

So here's your answer :-

When electric current is passed through water, it decomposes to give hydrogen and oxygen gas.

2H2O(l) -------> 2H2(g) + O2(g).
Water --------> Hydrogen + water (when Electric current is passed through it).

This process is known as "Electrolysis of Water".

Mainly it is Decomposition reaction.

Hope this helps you dear ✌✌
