Which of the following solutions will have the highest electrical conductivity?
C. Salt solution
Electrical conductivity of a solution depends on the concentration of free ions present in it. Distilled water is a very poor conductor of electricity due to the negligible concentration of H^+ and OH^- ions. Sugar and alcohol are covalent compounds and do not dissociate into ions when dissolved in water. Hence, their solutions are non-electrolytes and do not conduct electricity. Salt is an ionic compound and a strong electrolyte. It completely dissociates into its constituent ions in an aqueous solution, providing a large number of free ions for the conduction of electricity. Thus, the salt solution will have the highest electrical conductivity. Answer: Salt solution
