Question

The solubityof a compound in water is 6.8g/100ml at 0degreesC and 0.33g/100ml at 25degreesC.calculate the amount of water required to crystallize 10g of the compound.If the compound is collected at 25degreesC what is the maximum possible yield present?

Answers

Difference in solubility = 6.8-0.33 g
=6.47 g/100 ml.

10 g / ? ml. (of solution)
