The compound Mn3(PO4)2 is correctly named as manganese(II) phosphate, based on the rule of naming ionic compounds and considering the oxidation state of the manganese ion.
The correct name of the compound Mn3(PO4)2 is manganese(II) phosphate. This is based on the rule of naming ionic compounds. With ionic compounds, the metal cation's oxidation state is represented in Roman numerals in parentheses if the metal can have more than one charge state.
In this case, the Mn3+ cation in Mn3(PO4)2 has an oxidation state of +2 since the phosphate ions PO4^3- balance out 3 Mn ions. Therefore, the compound is correctly named manganese(II) phosphate.
