Question

The freezing point of benzoic acid remains relatively constant throughtout the freezing process. Is the same is true for the freezing point of a solution?

what? can you explain this for to me PLEASE!?

Answer 1

Benzoic acid freezes at 249 degrees Celsius while water freezes at 100. The solution is a binary solution meaning composed of two chemicals. The freezing process as you call it will vary between this region. First crystallizing water leaving benzoic acid behind as a liquid until a temperature is reached at 249 which will bring benzoic acid into solid form. So no the temperature will vary greatly during crustallization.
