The answer is a) True.
Ionic compounds typically consist of positively and negatively charged ions. When they are dissolved in water, these ions dissociate and separate from each other. This dissociation allows the solution to conduct electricity, as the free-moving ions can carry an electric current.
Water acts as a solvent and provides a medium for the ions to move. This is why electrolyte solutions, such as saltwater, conduct electricity quite well. In contrast, covalent compounds that do not dissociate into ions usually do not conduct electricity when dissolved in water.
