Sublimation
Sublimation is the process by which a solid substance transforms directly into a gas without passing through the liquid phase. This property can be utilized to separate a mixture of sodium chloride and naphthalene.
Procedure
- The mixture of sodium chloride and naphthalene is heated gently.
- Naphthalene, being a volatile compound, sublimes and turns into a gas.
- The naphthalene vapors are then collected and cooled down to form solid naphthalene crystals.
- The remaining solid, which is sodium chloride, can be separated from the naphthalene.
Advantages of using Sublimation
- Sublimation is a simple and effective method for separating mixtures of solids.
- It does not involve the use of any additional chemicals or solvents.
- It is a relatively quick process compared to other separation techniques.
Conclusion
In conclusion, the mixture of sodium chloride and naphthalene can be separated by sublimation. This method takes advantage of the differing sublimation points of the two compounds, allowing for their individual isolation.
