Chem: Ions, melting and boiling points

[EllChrTie]

For my post-lab in Chem, I cannot find the information relating to the melting and boiling points of the following ions: Ammonium (NH4^+) and Carbonate (CO3^2-). Does anyone have this relevant information? We are supposed to find outside sources, but I didn't come across any thus so far.

Try looking in a book of data. They usually have all sorts of useful data like melthing/boiling points

[Fuzzwood]

Ions do not have melting and boiling points. Only their salts have.

I don't think you can find mp or bp of other ions like the common ones, Na+ and K+. You should be looking for compounds.
