High purity dihydrogen is obtained by electrolysing

Explanation

To obtain high purity dihydrogen through electrolysis, follow these steps:

### Step 1: Set Up the Electrolysis Apparatus
- Use a suitable electrolysis apparatus which includes a container filled with water, platinum electrodes, and a power source.

### Step 2: Prepare the Electrolyte
- Add a small amount of acid (like sulfuric acid) or alkali (like sodium hydroxide) to the water. This is done to increase the conductivity of the water, allowing for efficient electrolysis.
