Mixture
A mixture is defined as a mass obtained by mixing up two or more chemically non-reactive substances in any proportion by weight. A homogeneous mixture is defined as a mass in which the particles of the components of the mixture are equally distributed. A heterogeneous mixture is defined as a mass in which the particles of components of the mixture are not equally distributed. This note gives further information about solubility, mixture, solution, colloids and suspensions.

Things to Remember
- A mixture is defined as a mass obtained by mixing up two or more chemically non-reactive substances in any proportion by weight.
- A homogeneous mixture is defined as a mass in which the particles of the components of the mixture are equally distributed.
- A heterogeneous mixture is defined as a mass in which the particles of components of the mixture are not equally distributed.
- Solution is defined as the homogeneous mixture of two or more than two substances that can be formed either by mixing suitable solid in liquid or by liquid in liquid.
- Colloid is a homogeneous mixture in which the diameter of particles of components ranges in between that of particles of a solution and suspension.
- Suspension is a heterogeneous mixture in which the diameter of the particle is 10-5 cm or larger.

Mixture
A mixture is defined as a mass obtained by mixing up two or more chemically non-reactive substances in any proportion by weight. There are two types of mixture. They are as follows:
1. Homogeneous mixture:
A homogeneous mixture is defined as a mass in which the particles of the components of the mixture are equally distributed. Examples: Sugar solution, air, alcohol water, brass, soda water etc
2. Heterogeneous mixture
A heterogeneous mixture is defined as a mass in which the particles of components of the mixture are not equally distributed. Examples: Smoke, Oily water, Sandy water, etc.
On the basis of the size the particles are divided into following types:
- Solution
- Colloids
- Suspensions
Solution
The solution is defined as the homogeneous mixture of two or more than two substances that can be formed either by mixing suitable solid in the liquid or by the liquid in liquid.
Solution = solute + solvent
Solute: It is the component of a solution, which gets dissolved into other substance to form a solution.
Solvent: It is the substance, which dissolves solute to form a solution.
Water: It is a universal solvent that has the capacity of dissolving many substances like common salts, copper sulphate, sugar, etc.
Alcohol: It found in the form of spirit and can dissolve resin and iodine.
Petrol and kerosene: It dissolves ghee, grease, oil, fat, etc and is used for removing clothes stain.
Ether: It is an organic solvent that can dissolve fat, oil, resin, etc.
Colloids
Colloid is a homogeneous mixture in which the diameter of particles of components ranges in between that of particles of a solution and suspension, i.e. a particle’s size ranges from 10-7 cm to 10-5 cm. The colloidal solution of liquid in liquid is called emulsion. Some of the examples of colloids are blood, milk, gum, wax, etc.
Suspensions
The suspension is a heterogeneous mixture in which the diameter of the particle is 10-5 cm or larger. Their particles are visible under a simple microscopic as well as to the naked eyes. Some of the examples of suspensions are sand water, muddy water, smoke in air, etc.
