Question

What happens when an electric current is passed through water?

Answer 1

Explanation:

If an electric current is run through water with a high purity, it will undergo a decomposition reaction known as "electrolysis." Water, being a molecule with polar charge distribution (more negative oxygen and more positive hydrogen), is broken down into hydrogen and oxygen upon exposure to a sufficiently strong electric current. The current causes half of the molecule to be attracted while the other half is repelled, ripping it in half.

On the other hand, if the water is not pure, it may act as a conductor, delivering an electric shock to any objects coming into contact with it.

Answer 2

Explanation:

When electric current is passed through water , it decomposes to give hydrogen gas and oxygen gas. Water splits up into H+ ions and OH- ions . Positive H+ ions will move towards the negative terminal that is cathode and OH- ions will move towards anode.
