Give the name and formula of the compound formed when a Mn2+ cation combines with a (PO4)3- anion. A. Manganese phosphate: Mn3(PO4)2 B. Magnesium phosphate: Mn2(PO4)3 C. Manganese sulfate: Mn2(PO4)3 D. Magnesium sulfate: Mn3(PO4)2 E. Manganese oxalate: Mn2(PO4)3-

A. Manganese(II) Phosphate Mn3(PO4)2

Explanation: The cation combines with anion through coloumbic forces to form an ionic compound.

The cation combines with anion in the ratio of 3:2 so as to form a neutral and stable compound named as Manganese(II) phosphate.

The IUPAC name of ionic compounds are written as:

First the name of the cation is written with its oxidation state in brackets. Then the name of the anion is written.

The answer for plato is Manganese(II) Phosphate Mn3(PO4)2
