The oxidation state of manganese(mn) in the given compound is +3.
The given compound;
Mn₃O₄
The oxidation state of the given compound is determined as shown below;
the oxidation number of oxygen (O) is -2
let the oxidation number of manganese (Mn) = x
3(x) + 4(-2) = 0
3x - 8 = 0
3x = 8
[tex]x = \frac{8}{3} = 2.67 \approx +3[/tex]
Thus, the oxidation state of manganese (mn) in the given compound is +3.
