Question

few drops of an acid are added to water in the electrolysis of water .explain why ?​

Answer 1

Answer:

because pure water does not undergo electrolysis process , it is essential to add a few drops of HCl or Sulphuric acid...

Answer 2

Explanation:

Water is a covalent compund hence doesn't ionises.

Pure water is a poor conductor of electricity, but for electrolysis, we need ions hence to make ionise water which is a polar covalent compound need some drop of acid and water is ionised and conduct electricity and electrolysis is carried out.
