If the liquid being distilled contains dissolved ammonia gas, where will it be bound after distillation is completed?
Correct answer: E. In the distillate
- A. Around the thermometer
- B. In the condenser
- C. In the circulating water
- D. In the heated flask
- E. In the distillate
Explanation
Since the dissolved ammonia is volatile below the boiling point of water, it will be found in the distillate. Some will also escape as a gas.

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.
