Answer:
Separation of Substances by Steam Distillation
Steam distillation is a technique used to separate substances based on their volatility and solubility in water. In this process, steam is passed through a mixture of substances, and the volatile components are vaporized and carried along with the steam. The steam and vapor mixture is then condensed, and the resulting liquid is collected.
Explanation of Answer:
The correct answer to the given question is option 'A', which states that the substances can be separated by steam distillation if they are steam volatile and insoluble in water. Let's understand why this answer is correct.
1. Steam Volatility:
- Steam volatility refers to the ability of a substance to vaporize or convert into a gaseous state when exposed to steam.
- Substances that are steam volatile have a higher tendency to vaporize and mix with steam during the distillation process.
- This property is important for effective separation as it allows the volatile components to be carried away with the steam and condensed later.
- If the substances are not steam volatile, they will not evaporate and be separated during steam distillation.
2. Insolubility in Water:
- Insolubility in water implies that the substances do not dissolve or mix with water.
- During steam distillation, the mixture is heated, and steam is passed through it.
- If the substances are insoluble in water, they will not dissolve in the condensed steam and can be easily separated.
- On the other hand, if the substances are soluble in water, they will mix with the condensed steam, making separation more challenging.
Conclusion:
In conclusion, the correct answer to the question is option 'A' - the substances can be separated by steam distillation if they are steam volatile and insoluble in water. This combination of properties allows the volatile components to vaporize and be carried away with the steam, while the insolubility ensures that they do not mix with the condensed steam.
