Question

Match the following compounds with their amount of current flow in aqueous solution.

• A. High current flow
• B. Low current flow
• C. No flow of current

Answer 1

Solutions conduct electricity when there are free ions present in it.

- Nitric acid $\left({\text{HNO}}_3\right)$ is a strong acid. It dissociate into its respective ions when dissolved in water as H⁺ and ${\text{NO}}_3$⁻ and these ions helps in conduction of electricity.

-Acetic acid${\text{(CH}}_{3}COOH)$ is a weak acid, so it does not dissociate completely into its ion i.e ${\text{CH}}_{3}COO⁻$ and H⁺. So conduction of electricity is low as compared to strong acid.

- Methane${\text{(CH}}_4)$ does not dissociate into ions when dissolved in water and hence does not conduct electricity.
