What are the different types of solutions?
✓

Answer

A solution consists of a solvent and a solute. Since the physical states of a solvent and a solute may be gaseous, liquid or a solid, there are nine types of solutions.
Types of solutionsSoluteSolventExamples
(A) Gaseous solution   
(1) Gas in gasGasGas  Air, mixture of non reacting gases and vapours
(2) Liquid in gasLiquidGasChloroform mixed with nitrogen gas
(3) Solid in gasSolidGasSmoke, fumes,$I _2$ in air
(B) Liquid solution   
    (1) Gas in liquidGasLiquid$CO _2$ in water, $0 cos$$N _2$ in chloroform
    (2) Liquid in liquidLiquidLiquidAlcohol in water
