what is volatile and non volatile solute. also, explain the importance of both and uses
A non-volatile solute does produce vapour at the boiling point of the solution. They have lower vapour pressure and higher boiling point.
A volatile solute produces vapour at the boiling point of the solution. At the same temperature, they have higher vapour pressure than non-volatile solutes.
Examples: Alcohol, ether, mercury, and gasoline.
