Question

How to seperate components from
mixture containing sulphun charcoal
potassium nitrates​

Answer 1

Answer:

Gunpowder is a mixture of sulphur, charcoal and potassium nitrate. When water is added to the mixture, potassium nitrate dissolves. The mixture is then filtered. The filtrate is potassium nitrate solution while the residue is a mixture of sulphur and charcoal. The filtrate is evaporated on a sand bath to obtain potassium nitrate back. When carbon disulphide is added to the residue, sulphur dissolves. When this mixture is filtered the filtrate is sulphur solution while the residue is charcoal. Leaving it open evaporates the sulphur solution. Carbon disulphide then evaporates and sulphur crystals are left behind.

Answer 2

Answer:

The mixture can be supported through following steps:

1. The mixture is mixed with the solution of potassium nitrate.

2. The mixture is filtered.

3. The filtrate will include the potassium nitrate whereas the residue will include the mixture of charcoal and sulfur.

4. The filtrate is exposure to air for evaporation.

5. The potassium nitrate will be obtained after this process.

6. The carbon disulphide is added to the residue the sulphur will dissolve by this process.

7. When mixture is filtered the filtrate is the solution of sulphur.

8. The residue will contain the charcoal.

9. The carbon disulphide when evaporate then sulpur crystal will be left.
