Question
An impure sample contains 0.74 g of impurities and 4.55 g of benzoyl acid. The sample is dissolved in 100 mL of water and heated. The solution is then cooled. How many grams of the impurity will crystallize when the solution has cooled?
The solubility of the impurity and benzoic acid in cold and hot water are given below:
Compound/ Cold water solubility/Hot water sol
Ben acid/ 0.42 g per 100 mL/ 5.79 g per 100 mL
Impurity/ 0.61 g per 100 mL/ 4.62 g per 100 mL
Are the crytals produced pure benzoic acid?
