Answer:

(a) Saturated solution. A solution in which no more solute can be dissolved at a given temperature

is said to be saturated at that temperature. For example, 35.7 g of NaCl can be dissolved in

100 ml of water at 20°C.

(b) Pure substance. A pure substance is made of only one type of atoms or molecules. Pure

substances have same colour and texture at given temperature and presure. Pure substance has a fixed melting and boiling point at constant pressure. Pure substance includes elements and compounds. For example, hydrogen gas, sodium chloride, water etc.

(c) Colloid. A substance is said to be in the colloidal state if its particle size lies betweenland 100 nm. A colloidal solution is heterogeneous in nature and consist of two phases i.e. dispersed phase or colloidal particles and dispersion medium in which colloidal particles are suspended eg

colloidal solution of starch in water

(d) Suspension. It is a heterogeneous mixture in which the particles of the solute do not dissolve

but remain suspended throughout the bulk of the material and the size of particles is more than 10-7 m. These particles can be seen with naked eye.
