i need a bit more information on iron sulphide the compound to describe it. and also iron and sulphur the mixture if you can describe that. the uses of it, properties if have any and any others. websites will be helpful too. Thank you.
Iron sulphide is a grayish coloured compound formed by the Synthesis of iron and sulphur, when iron fillings and powdered sulphur are heated in a test-tube. It ignites spontaneously in air and evolves hydrogen sulphide gas when dilute hydrochloric acid is poured over it. Its properties are independent of its constituent elements. Iron is black and ferromagnetic in nature and sulphur is a amorphous yellow element whereas iron sulphide is gray, non-magnetic and crystalline. The mixture of Iron and Sulphur is a heterogeneous solid-solid mixture. When dilute Hydrochloric acid is poured over the mixture it would emit hydrogen gas as only Iron reacts and sulphur doesn't. If one heats this mixture in a dry test-tube Iron(II) sulphide would be formed.
