Question

Is NaCl an electrolyte?

Answer 1

1. Yes, sodium chloride $\left(\mathrm{NaCl}\right)$ is an electrolyte because sodium chloride can break into its constituent ions when dissolved in a polar solvent.
2. Sodium chloride is a strong electrolyte and it completely ionizes into its ions i.e, one is a cation$\left({\mathrm{Na}}^{+}\right)$ and the other is an anion$\left({\mathrm{Cl}}^{-}\right)$.

Hence, $\mathrm{NaCl}$ is an electrolyte.
