Question

Manganese (Mn) has many possible oxidation numbers (+2 and +4 are just two of these). Write the correct formulas and names for the four compounds which combine manganese (in these oxidation states) with both bromine and oxygen.

Answer 1

Answer:

Oxide of manganese, Potassium permanganate, Manganese bromide and manganese oxide.

Explanation:

1. Manganese dioxide

Its chemical formula is $MnO_2$. It is +4 oxidation state. It is a black solid which is fairly stable.

2. Potassium permanganate

Its chemical formula is $KMnO_4$. It is commonly used in the laboratories as oxidizing agent. They appear black in color.

3 Manganese bromide

Its chemical formula is $MnBr_2$

4. Oxides of manganese

Chemical formula is $Mn_3O_4$

The most stable state of Manganese is +2 oxidation state.
