In a solution of an ionic compound, the movement of ions towards the opposite electrodes when electricity is passed through the solution allows the flow of electric current, contributing to the conduction of electricity.

In a solution of an ionic compound, the movement of ions contributes to the conduction of electricity by enabling the flow of charge. When the ionic compound dissolves in a polar solvent like water, the positively charged ions (cations) and negatively charged ions (anions) become mobile. Under the influence of an electric field, these ions migrate towards oppositely charged electrodes. The movement of ions allows the transfer of charge, creating an electric current. The higher the concentration of ions and their mobility in the solution, the better the electrical conductivity, making the solution conductive and completing the circuit.
