2.) In a recrystallization process involving sodium benzoate, what is the minimum vol- ume of boiling water needed to dissolve 0.200 g of sodium benzoate? The solubility of sodium benzoate in boiling water is 1 gram per 1.4 mL. About how much sodium benzoate will remain dissolved when the water is cooled to 25°C? The solubility of sodium benzoate at 25°C is 1 gram per 1.8 mL. Calculate the maximum mass of solid sodium benzoate that can be recovered when the cooled solution is filtered.
