How can we separate a mixture of sulphur and sugar?a)By the process of filtrationb)By the process of crystallisationc)By dissolving in carbon disulphide solutiond)By evaporationCorrect answer is option 'C'. Can you explain this answer?

Question

Accepted Answer

Sulphur dissolves in carbon disulphide whereas sugar remains undissolved. Hence, a mixture of sulphur and sugar can be separated using carbon disulphide as solvent.

Answer

Because sulphur dissolves in carbon disulphide whereas sugar remain undissolved. The sulphur solution containing sugar is filtered when sugar is obtained as a residue on the filter paper and sulphur solution is obtained as a filterate. On evaporating the filterate, carbon disulphide solvent is eliminated and solid sulphur remains behind.

Answer

When we add carbon disulphide sulphur will dissolve and sugar will not. we can separate the mixture then by filtration and evaporation.

Answer

Separating a mixture of sulphur and sugar can be achieved by dissolving the mixture in carbon disulphide solution. This method takes advantage of the different solubilities of sulphur and sugar in carbon disulphide.

1. Dissolving the mixture:
- Start by adding the mixture of sulphur and sugar to a beaker.
- Then, add a sufficient amount of carbon disulphide solution to the beaker.
- Stir the mixture gently to ensure proper dissolution.

2. Formation of two layers:
- After stirring, the carbon disulphide solution will form a layer at the bottom of the beaker, while the undissolved sulphur and sugar will remain as a separate layer on top.

3. Separating the layers:
- Carefully pour the carbon disulphide solution into a separate container, leaving behind the undissolved sulphur and sugar mixture.
- The carbon disulphide solution now contains only the dissolved sulphur.

4. Evaporation of carbon disulphide:
- Transfer the carbon disulphide solution to an evaporating dish or a shallow container.
- Allow the carbon disulphide to evaporate slowly in a well-ventilated area. This process can be expedited by placing the dish on a hot plate, but caution must be exercised due to the flammability of carbon disulphide.
- As the carbon disulphide evaporates, it leaves behind the pure sulphur in the dish.

5. Recovery of sugar:
- The undissolved sugar can be collected from the original beaker after pouring out the carbon disulphide solution. It can be further purified using methods like filtration or crystallization if necessary.

In summary, by dissolving the mixture in carbon disulphide solution, the sulphur is separated as a dissolved substance while the sugar remains undissolved. The subsequent evaporation of the carbon disulphide solution allows the recovery of pure sulphur, while the sugar can be collected separately.
