Homework Help: Chem

Posted by Jason on Tuesday, October 7, 2008 at 10:39am.

the solubility of a compound is 59g per 100 mL in boiling methanol and 30g per 100mL in cold methanol, whereas its solubility in water is 7.2g per 100 mL at 95 C and .22g per 100mL at 2C. Which solvent would be better for recrystallization of the compound? Explain.

Well this is my take on this. I calculated the recovery yeild of each and I get 49% for the first ans 90% something for the second. I pick the second solvent to be better because it produces a higher recovery rate. However, I am a bit confused I'm I right. Is this good reasoning?
