|
Which of the folowing concentration term is affected by temperature
|
|
molarity
|
|
|
molality
|
|
|
molefraction
|
|
|
none of these
|
Explanation:
Detailed explanation-1: -Molarity depends upon volume and volume changes with a change in temperature. So molarity is definitely affected by a change in temperature.
Detailed explanation-2: -Molarity gets affected as it is the number of moles per unit volume (volume increases with increase of temperature).
Detailed explanation-3: -So, molarity decreases as the temperature increases.
Detailed explanation-4: -Solution: Molarity of the concentration units is temperature dependent.
Detailed explanation-5: -So, changes in temperature will affect the value of molarity. Molality is not dependent upon any quantity that changes with temperature. So, it is temperature independent. Normality depends upon the volume of the solution.
