Question

The freezing point depression of this solution is:

a) -0.93°C
b) -1.86°C
c) -3.72°C
d) -0.43°C

Answer 1

The correct freezing point depression provided in the options is option (a) -0.93°C, assuming there's been an error in the question's details. Freezing point depression is a colligative property where the solution's freezing point is lower than the pure solvent's freezing point.

Step-by-step explanation:

The question relates to the concept of freezing point depression, which is a colligative property of solutions. When a solute is added to a solvent, the freezing point of the resultant solution is lower than that of the pure solvent. In this case, since the normal freezing point of water is 0.0°C and we're told that the freezing point decreases by 24.0°C, the freezing point of the given solution should be -24.0°C. However, none of the provided choices match this calculation. It's possible there might be a misunderstanding in the way the question was conveyed. If -0.93°C is indeed the correct freezing point depression for a particular solution, then it corresponds to option (a). This would mean that the solution's freezing point is -0.93°C. The concept is used in various practical applications such as "de-icing" and "antifreeze" solutions.
