Chemistry
State which of two — a solution of HCl in water or in toluene is an electrolyte, giving reasons.
Answer
Water being a polar solvent, ionizes the polar covalent HCl molecule into free ions. Hence, the solution of HCl in water exhibits acidic properties and is an electrolyte whereas toluene not being a polar solvent does not dissociate HCl molecule into free ions. Hence, the solution of HCl in toluene does not exhibit acidic properties and is a non electrolyte.
