en.wikipedia.org/wiki/Sulfate

The sulfate or sulphate (see spelling differences) ion is a polyatomic anion with the empirical formula SO 2− 4.Sulfate is the spelling recommended by IUPAC, but sulphate is used in British English.Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life.

Sulfate is a sulfur oxoanion obtained by deprotonation of both OH groups of sulfuric acid. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It is a sulfur oxoanion, a sulfur oxide, an inorganic anion and a divalent inorganic anion.

When the cation and/or the anion is a polyatomic ion, parentheses may be used to group the atoms in the ion together to write the formula. For example, the salt ammonium sulfate consists of the cation NH 4 + and the sulfate anion SO 4 2-. The formula of the salt is written as (NH 4) 2 SO 4.

"-ate" is used for the salt of the higher oxidation state of the element and "ite" for the salt of the next lower oxidation state. sulfate has the formula SO4-2 and "sulfite" has the formula SO3-2, with sulfur having an oxidation state of +6 in sulfate and +4 in sulfite.

Instead you get the following as the predominate species in solution: (NH4)3PO4 --> 2NH3(aq) + NH4+ + H2PO4^- And I'm not sure what she has in mind for the dissolving of epsom salts, which are hydrated magnesium sulfate. When it dissolves you get water of course and magnesium ions and sulfate ions.

The structure of the sulfite anion can be described with three equivalent resonance structures.In each resonance structure, the sulfur atom is double-bonded to one oxygen atom with a formal charge of zero (neutral), and sulfur is singly bonded to the other two oxygen atoms, which each carry a formal charge of −1, together accounting for the −2 charge on the anion.
