'

x

g

of NaCl is added to water in a beaker with a lid. The temperature of the system is raised form

1^{\circ} \mathrm{C}

25^{\circ} \mathrm{C}

. Which out of the following plots, is best suited for the change in the molarity

(M)

of the solution with respect to temperature?

[Consider the solubility of NaCl remains unchanged over the temperature range]

[2 Apr 2025 Shift 2]

Solution:

Volume is minimum at

4^{\circ} \mathrm{C}

, so molarity will be maximum at

4^{\circ} \mathrm{C}

.
