In which mode of expression, the concentration of a solution remains independent of temperature?

A

Molarity

B

Normality

C

Formality

D

Molality

Text Solution

Verified by Experts

The correct Answer is:
D
Molaity, normality, and formality are calaculated against the volume of the solution. The volume of the solution changes with change in temperature, therefore these quanities do not reamain constant with temperature.
Molality `(m) = ("Moles of solute")/("Mass of solvent in kg")`
The molality of a solution remains independent of temperature because it involes only mass, which is independent of temperature.
