Question

after analyzing the given graph a student concluded

(i)Solubility of a solution increased with the increase in the temperature of the solution

(ii)Solubility does not affect by increase or decrease in the temperature of the solution

(iii)Saturation level of a solution can be increased by increase in the temperature of the solution.

IV . At 90° C the dissolved amount of sodium chloride is maximum choose the correct conclusion from the following options.

(a) only 1
(b)Both I and III
(c) I,III, and IV
(d) only IV​

Answer 1

Answer:

Both I and III

Explanation:

Answer 2

Answer: (iii) Both (i) and (iii)

Explanation:

when temperature of solution is increases then the particles of solution gets excited and moves away from the each other forming space between them and therefore more amount of solute can be added.

hence,

solubility of the solution increases and also  the saturation level .
