Ncert Exercises & Solutions

Which of the following factor (s) affect the solubility of a gaseous solute in the fixed volume of liquid solvent?

(i) Nature of solute

(ii) Temperature

(iii) Pressure

a. (i) and (iii) at constant T

b. (i) and (ii) at constant p

c. (ii) and (iii)

d. Only (iii)

Choose the correct option

1. (a, b)

2. (b, c)

3. (c, d)

4. (a, d)

Hint: Gaseous solute solubility increases with pressure and decreases with temperature

Solubility of gaseous solute in the fixed volume of liquid solvent always depends upon the nature of solute but it depends upon

pressure at constant temperature and depends upon temperature at constant pressure.

Hence, (a) and (b) both are correct.
