nitrate, carbon and sulphur) can be separated.
​

Answer 1

Answer:

this is the flow chart of components of gunpowder

Explanation:

Gunpowder is a mixture of nitre (potassium nitrate) , sulphur and charcoal

Name of the method- filteration , evaporation and solvent extraction.

Steps-

1) Put the constituents in water. nitre will dissolve in water.

2) Filter the soln.

Filterate- water+nitre

Residue - sulphur+charcoal

3) Perform evaporation on the filterate.

Water will evaporate leaving nitre.

Solvent extraction-

4) Put the residue in carbon disulphide.

Sulphur will dissolve in this soln.

5) Filter the soln.

Filterate-carbon disulphide+sulphur

Residue- charcoal

6) Perform evaporation on the filterate.

carbon disulphide evaporates leaving sulphur.
