Definition of Solution And Types of solution on the basis of physical state of solute and solvent.

Solution : Definition of Solution :

✓ Solution is a homogeneous mixture of two or more than two components.

[ Homogeneous mixture : those mixture which have uniform properties and composition. ]

Components of solution :

There are two component in solution

1. Salute :

✓ One of the components of the solution that are lesser in amount is known as Solute.

2. Solvent :

Those component of the solution that are present in large amount, is known as Solvent.

Examples :

H2O + Salt

H2O + Sugar

On the basis of Solvent , solution are characterized into three groups ;

1. Solid solution

2. Liquid solution

3. Gaseous solution

1. Solid solution :

✓ Those solution in which solid components are present in solution as a solvent ( i.e. Higher in amount ) is known as Solid solution.

✓ Solid solution are of three types

(a) Solid solute + solid solvent

( Ex- mixture of copper and gold )

(b) Liquid solute + solid solvent

( Ex- mixture of Mercury and sodium )

( Ex- mixture of Hydrogen and palladium )

2. Liquid Solution :

✓ Those solution in which liquid components are present in solution as a solvent ( i.e. higher in amount ) is known as Liquid solution.

✓ Liquid solution are of three types

(a) Solid solute + Liquid solvent

(Ex- mixture of Glucose and water )

(b) Liquid solute + Liquid solvent

(Ex- mixture of ethanol and water )

( Ex- mixture of Oxygen and water )

3. Gaseous Solution :

✓ Those solution in which Gaseous components are present in the solution as solvent (i.e higher in amount ) is known as Gaseous solution.

✓ Gaseous solution are of three types

(a) solid solute + gaseous solvent

(Ex- mixture of Camphor and N2 gas ,

(b) Liquid solute + Gaseous solvent

( Ex - mixture of CHCl3- chloroform and N2 gas )

(Ex - Air , mixture of O2 gas and N2 gas )
