Consider the crystallization of sulfanilamide from 95% ethyl alcohol. If impure sulfanilamide is dissolved in the minimum amount of 95% ethyl alcohol at 40°C rather than 78°C (the boiling point of ethyl alcohol), how would this affect the percent recovery of pure sulfanilamide? Explain your answer.
it would lower the percent recovery since the impure sulfanilamide is not able to fully dissolve and crystallize as it slowly cools
