What is the role of sulfuric acid H2SO4 in electrolysis of water?

Answer 1

Electrolysis of pure water is very slow, and can only occur due to the self-ionization of water. Pure water has an electrical conductivity about one millionth that of seawater. It is sped up dramatically by adding an electrolyte (such as a salt, an acid or a base).

Answer 2

Because there is low concentration of ions in water and hence it is a poor conductor of electricity. So dilute sulphuric acid is added to increase the ion concentration in water so that electrolysis may be carried out faster.

Answer 3

Sulfuric acid is used as an electrolyte in the electrolysis of water to increase the conductivity of the solution. It helps to facilitate the flow of electricity between the electrodes, allowing for the breakdown of water into hydrogen and oxygen gases. Additionally, sulfuric acid can also help to prevent the oxidation of the electrodes, improving the overall efficiency of the process.

Answer 4

There are two reasons for this:

1. It improves the conductivity of the electrolyte.

2. If the solution is concentrated, it prevents the precipitation of copper(II) hydroxide.

Answer 5

To raise the electrical conductivity of the liquid.

Answer 6

It provides ions to the medium and serves as a catalyst.

Answer 7

The NaOH acts as a catalyst for the reaction.

Answer 8

AA

Answer 9

free ions
