Question

Which of the following concentration method depends on the temperature?​

Answer 1

Temperature affects a solution in various ways.

Explanation:

• Molarity of a solution is found out using the formula M = Vsolutionnsolute. So from this, we conclude that the V here is dependent on temperature.

• The molality of a solution is found out using  M = Wsolventnsolute. Here, Wsolvent represents the mass of the solvent. This mass is independent of temperature.

• So mass depends on volume and volume gets affects by temperature.

Answer 2

The concentration method which depends on temperature is molarity.

• Molarity is defined as the number of moles of solvent per volume of solution

• When temperature increases the volume of the solution decreases assuming the solution is in constant pressure conditions so molarity is dependent on temperature.

• All other concentration methods like ppm, molality, mole fraction, and mass percentage are independent of temperature.
