Formation of Iron(II) Sulfide

Fe + S → FeS

Tổng quan

Iron filings react with sulfur powder when heated to form iron(II) sulfide. This is a classic demonstration reaction in chemistry education, showing the difference between a mixture and a compound. Unlike the original mixture, iron sulfide cannot be separated with a magnet.
