How to Remove Black Oxide

It protects the metal from moisture and humidity and prevents rust. The appearance of black oxide on any metal object is a uniform black finish. When black oxide is not applied properly, it can result in variations in color, flaking or the development of rust. If rust development or flaking occurs, black oxide should be removed from the object.

Preparation and structure. FeS can be obtained by the heating of iron and sulfur:. Fe + S → FeS. FeS adopts the nickel arsenide structure, featuring octahedral Fe centers and trigonal prismatic sulfide sites.. Reactions. Iron sulfide reacts with hydrochloric acid, releasing hydrogen sulfide:. FeS + 2 HCl → FeCl 2 + H 2 S FeS + H 2 SO 4 → FeSO 4 + H 2 S

How to remove iron oxide

A simple method would be to hold a magnet to the mixture and the iron (ii) oxide would be separated, but not to a very pure extent. A far more effective method would be to add the mixture to water, this would dissolve the iron (ii) chloride and leave behind the oxide. You can then recover the iron (ii)chloride by evaporating the water. 2
