उत्तर
A solution of HCI gas in water turns blue litmus red and conducts electricity, while HCI gas dissolves in toluene and it has no effect because hydrochloric acid is a polar covalent compound. In polar solvent like water it ionizes to give hydrogen ions and also facilitates the movement of electrons to conduct electricity while it does not ionize in organic solvents like toluene.
