Question

distilled water doesn't conduct electricity whereas rain/top water does.

Answer 1

This is because distilled water does not have free ions.

Distilled water ; Distilled water is water that has virtually all of its impurities removed through distillation. Distillation involves boiling the water and re-condensing the steam into a clean container, leaving most if not all solid contaminants behind. The conduction of electricity takes place through charges i. e. ions, as no ions are present in the distilled water it does not conduct electricity. Rain Water ; the rain water contains dissolved gases like carbon di-oxide, sulphur dioxide etc, which generate acids like carbonic acid or sulphuric acid in presence of water. These acids get ionised and facilitate conduction of current . Hence, rain water conduct electricity.

Hope my answer helps you.

Answer 2

Answer:

Distilled water cannot conduct electricity because it does not contain ions while rain water conducts electricity as it contains ions due to presence of dissolved salts in it.
