Question 1 Report

The acid used in electrolysis of water is dilute

HNO3

CH3COOH

H2SO4

HCl

Answer Details

None of the given options are commonly used as the acid in the electrolysis of water. In fact, the most common acid used in the electrolysis of water is dilute sulfuric acid (H2SO4). The purpose of the acid in the electrolysis of water is to increase the conductivity of the water. Pure water is a poor conductor of electricity, but by adding a small amount of acid, it can become a better conductor. This is because the acid dissociates into ions in the water, which allows the electrical current to pass more easily through the solution. However, it's important to note that the acid used in the electrolysis of water is typically only slightly acidic or "dilute." This is because too much acid can cause unwanted side reactions and can also corrode the electrodes used in the process. Therefore, the acid is usually added in a small amount to achieve the desired conductivity without causing any harm to the equipment or the process itself.
