Verified Answer
In the laboratory, carbon disulphide is used as a solvent to separate...
(i) There will be no reaction. Carbon disulphide is a colourless liquid. Iron sulphide is an ionic compound while carbon disulphide is a nonpolar molecule. Iron sulphide is not soluble in carbon disulphide, and hence the carbon disulphide remains colourless.
(ii) When HCl is added to a mixture of iron filings and sulphur powder, then iron being more reactive than hydrogen will displace hydrogen from the acid, forming its salt instead. The sulphur powder will not react with HCl. Following is the reaction between Fe and HCl
Fe + 2HCl → FeCl2 + H2
