Well...yes and no.

It's important to understand what sulfide is. The "ide" suffix means the atom has a negative charge on it, basically. Same with hydride, H-. Or the halides, fluoride, chloride, bromide, iodide - F-, Cl-, Br-, I-.

It's an anion. So what is Sulphide? Well it's S-. Actually it's S2- with 2 negative charges.

Which nicely demonstrates something else about "ides", that they are usually the lowest common oxidation state of the element. You can often tell what that is by inspection but otherwise, just Google it.

Anyhow, so now we know sulfide is s2-. It's not really a liquid because...it's not really anything. It just exists in things. You're not going to see it just lying around and you're not going to observe it alone outside of some pretty harsh conditions.

It is a liquid in the sense that it may form in a liquid! If we have H2S (hydrogen sulfide! Note the ide in the name. Each hydrogen is H+ so the S is 2-...it's a sulfide even while part of a compound.) and manage to pluck off both hydrogens then, yea, we'll have sulfide floating around in the solution....albeit in an extremely impure state.

In conclusion, the name sulfide basically means sulfur and then describes that sulfur a little bit. It's S2-, whether part of a compound or not....whether a liquid, solid, gas, whatever.
