Question
The solubility data for compound A in 3 different solvents is given below. Calculate the solubility in how and cold solvents for each, then predict whether a recrystallization in these solvents will be effective and explain your reasoning. (12 pts) a) solvent #1: 0.5 g dissolves in 50 ml of hot solvent: 0.125 g recovered recovery: 24 solubility in hot solvent (in gny: 105 solubility in cold solvent in glu): 7 ST siL effectiveness: Your, we knou this of how hish the saf 13 in Cold Solvent b) solvent #2: 0.5 g dissolves in 2 L of hot solvent: 0.250 g recovered recovery: 50% solubility in hot solvent (in g/L) -sH .2yo s/L solubility in cold solvent (in g/L): 5 g)L effectiveness nutin it h s A lower in celd selvenr So it HA no very effe tive. c) solvent #3: 0.5 g dissolves in 60 mL of hot solvent; 0.475 g recovered recovery: solubility in hot solvent (in g/L): 8.? 3 s/l solubility in cold solvent (in glL): 12 5L effectiveness: gout, reurshnlliz tion Shon ve Perfumes with this savent, it has sdukil, tr tn hot solvent 4 Aer in cold suiventExplanation / Answer
It is correct. Recrystallization is more favourable to increased temperature. More the positive difference between solubility in hot and cold solvent, more better would be the recrystallization so definitely recrystallization would be more effective in #3 solvent.
