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.
d)When dilute HCI is added to it,FeS will react with dil HCI to form H2S gas which has smell of rotten eggs and will turn lead acetate paper black.
e)H2S gas is obtained and its properties are
Hydrogen sulfide is a flammable, colorless gas with a characteristic odor of rotten eggs. It is commonly known as hydrosulfuric acid, sewer gas, and stink damp..
