The sequence of steps for separating a mixture of salt, sand and camph...
The correct answer is option 'C': Sublimation, adding water, filtration, evaporation.
1. Sublimation:
The first step in separating the mixture of salt, sand, and camphor is sublimation. Sublimation is the process by which a solid substance directly changes into its gaseous state without going through the liquid state. In this case, camphor undergoes sublimation at room temperature, meaning it evaporates and turns into gas. By heating the mixture, the camphor will sublimate and separate from the salt and sand.
2. Adding water:
After sublimation, we need to add water to the remaining mixture. By adding water, the salt will dissolve, while the sand remains insoluble. This step helps to separate the salt from the sand.
3. Filtration:
Once the water is added, the mixture needs to be filtered. Filtration is the process of separating a solid from a liquid by passing it through a filter. In this case, the mixture of sand and water can be poured through a filter paper or a sieve. The sand particles will be retained on the filter, while the saltwater solution will pass through.
4. Evaporation:
After filtration, we are left with a saltwater solution. To separate the salt from the water, we need to evaporate the water. Evaporation is the process of converting a liquid into a gas by heating it. By heating the saltwater solution, the water will evaporate, leaving behind solid salt crystals.
Therefore, the correct sequence of steps for separating the mixture of salt, sand, and camphor is sublimation, adding water, filtration, and evaporation. This sequence ensures that each component is separated based on its unique properties, such as sublimation, solubility, and boiling point.

- Sublimation: First, heat the mixture. Camphor sublimes, meaning it will change directly from a solid to a gas and can be separated from the mixture.
- Adding water: After removing camphor, dissolve the salt in water, since salt is soluble in water, but sand is not.
- Filtration: Use filtration to separate the sand from the saltwater solution. Sand will remain as the residue, while the salt will dissolve in the water.
- Evaporation: Finally, evaporate the water from the salt solution to obtain the salt crystals.
So, the correct sequence is C: Sublimation, adding water, filtration, evaporation.
