A mixture of common salt ,sulphur,sand and iron filings is shaken with carbon disulphide  and filtered through a filter paper.The filtrate is evaporated to dryness in a china dish .What will be left in the  dish after evaporation?

Dear Student,

Please find below the solution to the asked query:
When a mixture of common salt , sand , iron filings and sulphur is shaken with carbon disulphide, only Sulphur dissolves in it to form a yellow coloured liquid.[ NaCl will not dissolve in CS2 because it is a non -polar solvent].
The mixture is filtered through a filter paper ,NaCl, sand and Iron filings remain as the residue.[in the filter paper].When ‚Äčthe filtrate is evaporated to dryness in a china dish ,and cooled , Sulphur particles will be left in the china dish.

Regards
