Question 11 • IA-Chemistry A Survey of Chemistry A
Manganese(IV) has a +4 charge, while each sulfate ion (SO₄) has a −2 charge. Two sulfate ions balance one manganese ion, giving the neutral formula Mn(SO₄)₂. Therefore, the correct choice is Mn(SO₄)₂; MnSO₄ would pair manganese with only one sulfate ion.
