$\underline{\underline{ \bf Question}}$

Why an electrolyte be dissolved in pure water only for electrolysis ?

$\purple{ \huge\frak{Reason}}$

No , we can't use pure water for electrolysis rather we use acidulated water most probably Hydrochloric or Sulphuric Acid (dilute) is added in water. The reason behind this is that Electrolysis of acidulated water considered to be an example of catalysis because pure water is not good conductor of elecricity but when acid is added it catalyses the ionisation of water and water is dissociated into H+ and -OH ions.

This is why pure water can't conduct electricity even during the electrolysis when there are many ions in the solution. IN pure water there is no chance for electricity conduction as it has no free ions. It contains only H2O molecules.

Thankyou
