Question

3. What happens when electrodes are immersed in water and a current is passed? Which electrode will wear out faster and why​

Answer 1

Answer:

In this case, when oxygen is released at the anode, bubbles of oxygen react with the anode and causes its wearing faster

Explanation:

this is your answer.. hope ot helps you :)

Answer 2

Answer:

The anode will wear out faster.

Explanation:

When electrodes are immersed in water and a current is passed through it bubbles of oxygen and hydrogen are produced.

Oxygen bubbles are formed on the electrode which is connected to the positive terminal of the battery that is the anode and the hydrogen bubbles are formed at the negative terminal which is the cathode.

At the anode, the released oxygen gas reacts with it and causes it's wearing faster.

Hence anode will wear out faster.
