Question
Describe the bulk preparation of hydrogen by electrolytic method. What is the role of an electrolyte in this process?
✓
Answer
Electrolysis of acidified water using platinum electrodes gives hydrogen.
$2\text{H}_2\text{O}(\text{l})\xrightarrow[\text{Traces of acide/ base}]{\text{Electrolysis}}2\text{H}_2(\text{g})+\text{O}_2(\text{g})$
Here, the role of an electrolyte is to make water conducting.
