The solubility of acetanilide is 3.53 g in 100 ml of chloroform at 0 °c, and 29.1 g in 100 ml of chloroform at 60 °c. what is the maximum percent recovery that can be achieved for the recrystallization of acetanilide from chloroform?

The indication from which one can determine how much of active ingredient is recovered after purification method is said to be a percent recovery.

The formula for percent recovery is:

The solubility of acetanilide in 100 ml of chloroform at

The solubility of acetanilide in 100 ml of chloroform at

Substituting the values in the above formula:

%.

Hence,  the maximum percent recovery that can be achieved for the recrystallization of acetanilide from chloroform is %.
