What is sulphate and sulphide?
Sulphate and sulphite are the polyatomic ions of sulphur and are formed by the reaction of sulphur with oxygen atoms.
Is sulfur S or S2?
When sulfur reacts with an active metal, it can form the sulfide ion, S2 –. This is not the only product that can be obtained, however. A variety of polysulfide ions with a charge of -2 can be produced that differ in the number of sulfur atoms in the chain.
