Aqueous hydrogen chloride reacts with potassium manganite (VII) to produce chlorine gas, while a solution of hydrogen chloride in methylbenzene has no effect on potassium manganite (VII).Explain this observation.

Hydrogen chloride in water ionizes to form hydrogen and chloride ions hence showing acidic properties. In methylbenzene however it remains in
molecular form and does not display acidic properties.
