Question

Why does salt when added to water makes water more conductive to electricity?

Answer 1

Answer:

salt contains both ions negative and positive ions

Explanation:

In fields farmers get produced electricity by the use of the salt

Answer 2

Answer:

Salts, or in fact any element, can split into ions only when in aqueous solution, i.e., when mixed with water.

And they can only carry charge if they are in ions.

For example - NaCl becomes $Na^{+}$ and $Cl^{-}$ and henceforth carry either a positive or a negative charge.
