Question

How to separate the components from a mixture containing sulphur ,salt, charcoal and iron ?

Answer 1

The iron can be separated by magnetic separation.

Then dissolve the mixture in carbon disulphide . In this process the sulphur is dissolved in the carbon disulphide. Filter the mixture and boil the carbon disulphide to get the sulphur.

Next dissolve the mixture in water. By doing this the salt dissolves in the water while the charcoal is left behind. Filter the solution to get the charcoal and then use the evaporation method to get back the salt.
