Question

a)Give any one point of difference between true solution, colloidal solution and
suspension
b) 20g of sodium chloride dissolved in 100mL of water. How will you test whether the
given solution is saturated or unsaturated at the given temperature,
c) Suggest any one method by which we can increase the solubility of saturated
solutions
​

Answer 1

a. The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.

b. Thus, to test if a solution is saturated or not, we need to add sodium chloride, if it dissolves then it is not saturated and if it does not dissolve then its unsaturated

c. The solubility of saturated solutions can be increased by increasing the temperature (heating) of that particular solution.

Answer 2

Question 1 :-

Give any one point of difference between true solution, colloidal solution and

suspension

Answer:-

The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.

Question 2 :-

20g of sodium chloride dissolved in 100mL of water. How will you test whether the

given solution is saturated or unsaturated at the given temperature

Answer:-

A solution is said to be saturated if it has with the maximum possible amount of solute that it can dissolve whereas a solution is said to be unsaturated if a solution contains less than the maximum amount of solute.

Thus, to test if a solution is saturated or not, we need to add sodium chloride, if it dissolves then it is not saturated and if it does not dissolve then its unsaturated.

Question 3 :-

Suggest any one method by which we can increase the solubility of saturated

solutions

Answer:-

The solubility of saturated solutions can be increased by increasing the temperature (heating) of that particular solution.
