Question

Two students A and B got the mixture of iron and sulphur.A heated this mixture strongly but B kept it as such.They divided the mixture further into two parts and did same test.Tabulate their observation when
a)Both added CS2 in one part
b)both used magnets to separate its constituents in another part

Answer 1

(a)Sulfur (I use the U.S. spelling) is very slightly soluble in carbon disulfide(cs2) and iron is not, so the sulfur dissolves and the solution turns very pale yellow. The iron powder sinks to the bottom and doesn't dissolve, so you can pour off the solution and evaporate it and recover the sulfur.

(b)If they use magnet so iron will be easily separated from mixture...............................hope it helps u................

i am not sure in  b part
