What's the difference between sulphate and sulphide?

Hi, I'm a bit stuck on when something is sulphate and and when something is sulphide.
I know you would say copper sulphate as a reaction with sulphuric acid, but I'm stuck as to why.
Thanks.

Well the sulphate is the SO4 ion. It has a charge of -2
The sulphide is the just the S ion. It has a charge of -2 also.
Hope this helps

Sulfate involves the polyatomic ion SO4 (2-).

Sulfide involves a compound with just S (2-) as the anion.

p.s. there is also sulfite SO3 (2-)
