Explanation

A solution is homogeneous mixture of two or more chemically non-reacting substnaces. Types of solutions. There are nine types of solution types of solution examples.
Gaseous solution (a) gas in gas air, mixture of `O_(2)` and `N_(2)`. Etc.
(b). Liquid in gas water vapour.
(c) solid in gas comphor vapours in `N_(2)` gas smoke etc.
liquid solution
(a). Gas in liquid `CO_(2)` dissolved in water (aerated water). and `O_(2)` dissolved in water etc.
(b). Liquid in liquid ethanol dissolved in water etc.
(c). Solid in liquid sugar dissolved in water, etc
Solid solutions
(a). Gas in solid solution of hydrogen in palladium
(b). liquid in solid amalgams e.g., Na-Hg
(c). Solid in solid gold ornamens (Cu/Ag with Au).
