Problems and exercisesCrystallization
1. The ideal solvent
Which conditions must a good solvent meet to crystallize a compound?
2. Fast or slow
Why is it best to cool the hot solution slowly?
3. How much is recovered?
The solubility of benzoic acid in water is 6.8 g/100 mL at 95 °C and 0.34 g/100 mL at 25 °C. If you crystallize 5.0 g from the minimum amount of water at 95 °C and cool to 25 °C, what is the most you can recover?
