Question

Distilled water is a good conductor of electricity.

• A. True
• B. False

Answer 1

The correct option is B False

• Distilled water is a pure form of water that does not contain any solute in it.
• Therefore it cannot conduct electricity because it does not contain ions while rainwater contains dissolved salts and acids which dissociate into ions and conducts electricity.
• But when we add caustic soda to it, it becomes a conductor of electricity. Caustic soda or Sodium hydroxide ($\mathrm{NaOH}$) breaks down into its constituents, cation$\left({\mathrm{Na}}^{+}\right)$, and anion $\left({\mathrm{OH}}^{-}\right)$ and conducts electricity through distilled water.

Therefore, the given statement is false.
