ΔT f = -1.855 × 0.262 = -0.486 o C Calculate the freezing point of the solution: T f (solution) = normal freezing point + ΔT f T f (solution) = 0.000 - 0.486 = -0.486 o C Calculate the boiling ... Web24 jul. 2024 · All water does not freeze at the same time. Using the PAC we can calculate when the water starts to freeze. This is called the freezing point or FP. So at the FP we have 0% frozen water. When water starts to freeze the concentration of the sugars increases resulting in a higher PAC for the remaining water.
