Consider a crystallization of sulfanilamide in which 10 mL of hot 95% ethyl alcohol is added to 0.10 g of impure sulfanilamide. After the solid has dissolved, the solu-tion is cooled to room temperature and then placed in an ice-water bath. No crys-tals form, even after scratching with a glass rod. Explain why this crystallization failed. What would you have to do at this point to make the crystallization work? You should assume that starting over again with a new sample is not an option. (You may need to refer to Technique 11, Figure 11.2.
