Concentration terms like mass percentage, ppm, mole fraction and molality do not depend on temperature, However, molarity is a function of temperature because.
A
Volume depends on temperature and molarity involves volume
B
Molarity involves non-volatile solute while all other terms involves volatile solute.
C
Number of moles of solute change with change in
temperature.
D
Molarity is used for polar solvents only.
Answer
Volume depends on temperature and molarity involves volume
Explanation
Solution
Molarity is defined as the number of moles of solute dissolved in one litre of solution since volume changes with change in temperature, the molarity also changes. Other terms involve mass which does not change with temperature.
