18.

A student makes an electric circuit using an LED, a battery and connecting wires to test the conductivity of distilled water. The student notices that the LED does not glow. He replaces the distilled water with a salt solution and observes that the LED glows. How does the salt solution help the LED to glow?

Salt solution contains ions which makes it conductive and allows the electricity to flow through it.

Salt solution is covalent in nature and conducts electricity.

Salt solution has a low melting point which allows the current to flow through it.

Salt solution has a high boiling point which allows the flow of current in the circuit without getting hot.
