explain the following given examples (a) saturated solution (b) pure aubstance (c) colloid (d) suspension
Answers
(b) Pure Substance: Any substance is said to be pure if and only if it is made up of single type of particles means all the particles of that substance should be of same chemical nature. For example water, sugar, salt etc.
(c) Colloid: A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. When a beam of light is passed through a colloid then the path of the light becomes visible. For example milk, smoke etc.
(d) Suspension: A suspension is a heterogeneous mixture in which solids are dispersed in liquids. The solute particles in suspension do not dissolve but remain suspended throughout the medium. For example Paints, Muddy water chalk water mixtures etc.
Answer :-
_______________________________
Saturated Solution :
The Solution in which no more solute can be dissolved in the same amount of solvent at a particular temperature is called saturated solution.

Pure Substance :
The substance which always has the same characteristic at a given temperature and pressure is called Pure Substance.

Colloid :
Colloid consists of particles bigger than that of solution, smaller than that of suspension. It appears to be homogeneous but actually it is heterogeneous.

Suspension :
It consist of particles which are larger in size and are visible with naked eyes. It is heterogeneous.
