In electrolysis of water, which gas is produced at the anode

In the electrolysis of water, oxygen gas is produced at the anode. Here's a step-by-step explanation:

1. Electrolysis involves the breaking down of a substance using electricity. In the case of water, it is broken down into hydrogen and oxygen.

2. Water (H2O) is made up of hydrogen (H2) and oxygen (O2). When electricity is passed through water, it splits the water molecules into these two gases.

3. The anode is the positive electrode in electrolysis. It attracts the negatively charged ions. In water, oxygen is the negatively charged ion.

4. Therefore, during electrolysis, oxygen is attracted to the anode where it is released as oxygen gas.

So, the gas produced at the anode during the electrolysis of water is oxygen.
