Explain the types of solutions based on the physical states of solute and solvent with suitable examples.

(N/A) Solutions are classified into $9$ types based on the physical states of solute and solvent:
$1$. Gas in Gas: Example,mixture of $O_2$ and $N_2$ gases.
$2$. Liquid in Gas: Example,chloroform mixed with $N_2$ gas.
$3$. Solid in Gas: Example,camphor in $N_2$ gas.
$4$. Gas in Liquid: Example,$O_2$ dissolved in water.
$5$. Liquid in Liquid: Example,ethanol dissolved in water.
$6$. Solid in Liquid: Example,glucose dissolved in water.
$7$. Gas in Solid: Example,solution of $H_2$ in palladium.
$8$. Liquid in Solid: Example,amalgam of mercury with sodium.
$9$. Solid in Solid: Example,copper dissolved in gold (alloys).
