In this laboratory setup for distillation, where does the vaporization take place?
Correct answer: D. In the heated flask
- A. Around the thermometer
- B. In the condenser
- C. In the circulating water
- D. In the heated flask
- E. In the distillate
Explanation
Option d is correct because in a laboratory setup for distillation, vaporization takes place in the heated flask. This is where the liquid is heated, leading to the formation of vapor or gaseous form of the substance.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
