Final answer:
The difference in freezing point depressions between the HCl solution in benzene and in water can be explained by the dissociation of HCl into ions.
Step-by-step explanation:
The difference in freezing point depressions between the HCl solution in benzene and in water can be explained by the dissociation of HCl into ions.
When HCl dissolves in water, it dissociates into H+ and Cl- ions. This increases the number of solute particles in the solution, leading to a greater freezing point depression.
In benzene, however, HCl does not dissociate into ions. Therefore, the freezing point depression is lower compared to the HCl solution in water.
