Explain the following giving examples
(a) saturated solution
(b) pure substance
(c) colloid
(d) suspension
Answers
Answer:
(a)The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.
(b)Pure substances are defined as substances that are made of only one type of atom or molecule. The purity of a substance is the measure of the extent to which a given substance is pure. The physical properties of a pure substance include well-defined melting and boiling points.
(c)a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.
(d)the action of suspending someone or something or the condition of being suspended.

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.
