MCQ
Which one of the following depends upon variations in temperature?
  • ✓
    Both Normality and Molarity
  • B
    Normality
  • C
    Molarity
  • D
    Molality
✓

Answer

Correct option: A.
Both Normality and Molarity
(a) Both Normality and Molarity
Explanation: Since Molarity and Normality both the modes of expression to represent the strength of a solution are volumedependent, a variation in temperature of the solution results in a change in concentration or strength of the solution. It is due to the thermal expansion of liquids.
