Benzoic acid is a organic compound. Its crude sample can be purified by crystallization from hot water. What characteristic differences in the properties of benzoic acid and the impurity make this process of purification suitable?
Options
- ABenzoic acid can be purified by hot water because impurities present in benzoic acid are either insoluble in w
- BBenzoic acid has high temperature.
- CBenzoic acid forms a colored solution in hot water, allowing for easy separation.
- DBenzoic acid and the impurity have identical properties, but the process relies on temperature control.
Correct answer
A. Benzoic acid can be purified by hot water because impurities present in benzoic acid are either insoluble in w
Step-by-step solution
Correct Option is : (A) Benzoic acid can be purified by hot water because impurities present in benzoic acid are either insoluble in water or more soluble in water to such an extent that they remain in solution as the mother liquor upon crystallization.
