The reason for no crystallization of the sulfanilamide in the give experimental procedure needs to be explained. Concept Introduction : Crystallization is explained as a procedure by which formation of crystal or solid takes place by precipitating them from the solution. It takes place by either supercooling the solution liquid or by supersaturated solvent.

Expert Solution & Answer

Answer to Problem 1Q

Crystallization of sulfanilamide did not occur because of the proper ratio of solute and solvent is not taken in dissolving.

Explanation of Solution

Given Information:

10 mL volume of 95% ethyl alcohol is added to impure sulfanilamide of mass 0.10 g. After dissolving the solid, solution is cooled to room temperature and placed on ice-water bath for crystallization.

Sulfanilamide contains both polar sulfonamide,amine and non-polar benzene groups in its molecule, Thus, to solvate it properly, it requires a solvent of intermediate polarity. Solution of 95% ethyl alcohol contains 5% water (which is highly polar) so it is a good choice.The problem in the given experiment is not with the chosen solvent pair, but with the amount of the solvent used for dissolving the solute. At high temperatures, small quantity of solvent is to be taken for dissolving maximum quantity of solute for recrystallization, which then can be extracted when the solution is cooled, otherwise the solute would not be removed as crystals.
