When saccharin is added to pure water, the freezing point of the resulting solution drops to -5.0C, Calculate the freezing point depression of the aqueous saccharin solution. Note: freezing point of pure water is O.0C...
Stuck thanks so much!
To calculate the freezing point depression of the aqueous saccharin solution, we need to determine the difference between the freezing point of the pure solvent (water) and the freezing point of the solution.
The freezing point depression (∆Tf) can be calculated using the equation:
∆Tf = Tf(solvent) - Tf(solution)
In this case, the freezing point of the pure solvent (water) is 0.0°C, and the freezing point of the solution is -5.0°C.
∆Tf = 0.0°C - (-5.0°C)
∆Tf = 5.0°C
Therefore, the freezing point depression of the aqueous saccharin solution is 5.0°C.
