Question

The solubility of a compound is 59g per 100mL in boiling methanol and 30g per 100mL in cold methanol, whereas its solubility in water is 7.2g per at 95 degrees Celsius and 0.22g per 100mL at 2 degrees Celsius. Which solvent would be better for recrystallization of the compound? Explain.

Answer 1

I would use H2O as the solvent because the methanol dissolves 30 g/100 mL whereas you lose only 0.22 g/100 in water.

Answer 2

i will go for methanol
