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 involve volatile solute
- c)Number of moles of solute change with change in temperature
- d)Molarity is used for polar solvents only
Correct answer is option 'A'. Can you explain this answer?

Concentration terms like mass percentage, ppm, mole fraction and molal...
Molarity of a solution is defined as the number of moles of solute dissolved per litre of solution. Since volume depends on temperature and changes with change in temperature, therefore, the molarity will also change with change in temperature. On the other hand, mass does not change with change in temperature, and therefore, concentration terms such as mass percentage, mole fraction and molality which do not involve volume are independent of temperature.

Explanation:
Volume dependence on temperature:
- Molarity is defined as the number of moles of solute dissolved in one liter of solution.
- Volume is a key factor in molarity calculation. As volume changes with temperature due to thermal expansion or contraction, molarity is affected.
Effect of temperature on volume:
- The volume of a liquid generally increases with an increase in temperature, which results in a decrease in molarity.
- Conversely, a decrease in temperature leads to a decrease in volume and an increase in molarity.
Impact on molarity:
- Since molarity involves the volume of the solution, any change in temperature directly affects the volume and consequently the molarity of the solution.
- Therefore, molarity is a function of temperature as it is dependent on the volume of the solution.
Conclusion:
- The dependency of molarity on temperature arises due to the influence of temperature on the volume of the solution. Other concentration terms like mass percentage, ppm, mole fraction, and molality remain unaffected by temperature changes as they do not involve volume in their calculations.
