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

Options

A. Molality
B. Molarity
C. Formality
D. Normality

Answer

1

Explanation

While expressing molarity, we take moles of solute per `1000 g` of solvent. Since the no. of moles and mass are independent of of temperature, the answer is (1).
Each method of expressing concentration of the solutions has its own merits and demerits. Mass%, ppm, mole fraction and molarity are independed of temperature, whereas molarity is a function of temperature. This is because volume depends on temperature and the mass does not. Similarly formally and noemally involving depend on temperature.
