What are Sulfides?

Question by Guest | 13/05/2018 at 21:13

Unfortunately, I can not find an easy-to-understand description of sulfides. We will write a paper next week and I need a good understandable description of sulfides as soon as possible.

Sulfides are salts or other derived substances from hydrogen sulfide (H2S).

Salts are chemical compounds made up of positively charged ions (cations) and negatively charged ions (anions). Sulfide salts contain the anion S2-.

An example of a sulfide found in nature is the iron sulfide FeS, which consists of the cations Fe2+ and the anions S2- and can be easily prepared by briefly heating iron powder and sulfur powder. Another example is sodium sulfide Na2S, where correspondingly 2 Na+ are combined with one S2-.

While sulfides are salts with the anion S2- , sulfites are salts with the anion SO32- and sulfates salts with the anion SO42-.
