1.	Describe the process of separation of constituents of gum powder.
Answer» SOLUTION :Separation of the components`(KHO_(3)("nitre")+"carbon+sulphur) of gunpowder"` Procedure : Carbon disulphide is added to beaker containing gunpowder sulphur GETS DISSOLVED in carbon disulphide. Theis mixture is then filtered with the help of a filter paper. The filtrate obtianed taken in flat vessel and exposed to air till carbon disulphide vapourises away leaving behind sulphur. The residue obtained containing carbon powder and nitre. It is taken in a beaker containing hot water. Nitre dissolves in hot water This mixture is then filtered with the help the of filter paper. Carbon powder is left on the filter paper as a residue which is collected after DRYING. The filtrate on EVAPORATION to dryness by heating gives solid nitre. Thus the constituents of gunpowder are separated.
