Question

Impure benzoic acid was dissolved in hot water. the container of solution was placed in an ice-water bath instead of being allowed cooling slowly .what will be the result of cooling the solution in this manner

Answer 1

The rapid cooling of an impure benzoic acid solution in an ice-water bath will result in the formation of pure benzoic acid crystals.

Step-by-step explanation:

When impure benzoic acid is dissolved in hot water and then rapidly cooled in an ice-water bath, the result is the formation of crystals of pure benzoic acid. This is because cooling the solution quickly does not allow enough time for impurities to incorporate into the growing crystals. As a result, the impurities are left behind in the solution, while the pure benzoic acid crystallizes out.

Answer 2

The result of cooling in this manner is that impurities will be removed from the impure benzoic acid resulting in a more purified benzoic acid. The method described above is known as re-crystallization and it is often used to remove impurities from substance by choosing conditions that will favour the re-crystallization of the substance only, thus leaving the impurities behind.
