Question

When electrodes are immersed in water and electricity is passed, the bubbles formed on the negative terminal is actually________ gas.​

Answer 1

Required Answer:-

When electrodes are immersed in water and electricity is passed, the bubbles formed on the negative terminal is actually Hydrogen (H2) gas.

Explanation:-

Electrolytic decomposition is the process of breaking down H2O or water molecule into its constituent elements Hydrogen and Oxygen$.$

About the reaction:

• We need a electrolytic tank with acidulated water (A minute amount of acid).
• Electricity is passed through the solution by a battery or a cell.
• The cation forming gas H2 moves towards the negative terminal and the anion forming gas O2 moves towards the positive terminal.

Refer to the attachment for the experimental setup. The required reaction of electrolysis of water is: 2H2O ➙ 2H2 + O2 (Liquid states to form gases).

Answer 2

☆Answer☆

When electrodes are immersed in water and electricity is passed, the bubbles formed on the negative terminal is actually Hydrogen (H2) gas.

Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas.
