Question

4. Explain the following giving examples.
(a) saturated solution
(b) pure substance
(c) colloid
(d) suspension​

Answer 1

Answer:

(a) saturated solution

Explanation:

(a) Saturated solution: Solution in which no more solute can be dissolved at a particular temperature is known as saturated solution. ... The solute particles in suspension do not dissolve but remain suspended throughout the medium. For example Paints, Muddy water chalk water mixtures etc.

Answer 2

Answer:

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

(a) Saturated solution. A solution in which no more solute can be dissolved at a given temperatureis said to be saturated at that temperature. For example, 35.7 g of NaCl can be dissolved in

(a) Saturated solution. A solution in which no more solute can be dissolved at a given temperatureis said to be saturated at that temperature. For example, 35.7 g of NaCl can be dissolved in100 ml of water at 20°C.

For example, 35.7 g of NaCl can be dissolved in100 ml of water at 20°C.(b) Pure substance. A pure substance is made of only one type of atoms or molecules. Pure

(a) Saturated solution. A solution in which no more solute can be dissolved at a given temperatureis said to be saturated at that temperature. For example, 35.7 g of NaCl can be dissolved in100 ml of water at 20°C.(b) Pure substance. A pure substance is made of only one type of atoms or molecules. Puresubstances 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.

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

or colloidal particles and dispersion medium in which colloidal particles are suspended egcolloidal solution of starch in water

or colloidal particles and dispersion medium in which colloidal particles are suspended egcolloidal solution of starch in water(d) Suspension. It is a heterogeneous mixture in which the particles of the solute do not dissolve

or colloidal particles and dispersion medium in which colloidal particles are suspended egcolloidal solution of starch in water(d) Suspension. It is a heterogeneous mixture in which the particles of the solute do not dissolvebut 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.
