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.
