The solubility of acetanilide is 0.53 g in 100 ml of ice‑cold water, and 5.50 g in 100 ml of boiling water. what is the maximum percent recovery that can be achieved for the recrystallization of acetanilide from water?

MPR=90,36%

Explanation:

The recrystallization is a purification process where the solid to purify is dissolved in an appropriated dissolvent and then, changing the conditions the solubility changes and that solid (that was in solution before) precipitates and form crystals.

In this case, for boiling water 5.50 g of  acetanilide could be dissolved and then cold the water, so the mass of crystals formed will be  

The maximum percent recovery is then

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
