The solution is usually a liquid, but not always. It might also include a mixture of two solids like in alloys, and a mixture of gases, such as air.
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
Types of Solution
Depending upon the physical states of solute and solvent, we can classify solutions into nine different types.
|S.No||Types of Solution||Solute||Solvent||Examples|
|1||Solid-solid||solid||solid||Alloys like brass, bronze etc.|
|2||Solid-liquid||solid||liquid||The solution of sugar, salt etc in water.|
|3||Solid-gas||solid||gas||Sublimation of substances like iodine, camphor etc into the air.|
|4||Liquid-solid||liquid||solid||Hydrated salts, mercury in amalgamated zinc, etc.|
|5||Liquid-liquid||liquid||liquid||Alcohol in water, benzene in toluene|
|6||Liquid-gas||liquid||gas||Aerosol, water vapour in the air.|
|7||Gas-solid||gas||solid||Hydrogen absorbed in palladium|
|9||Gas-gas||gas||gas||A mixture of gases, etc|
