What is the oxidation number of manganese in mno41−? +3 +4 +7 +8

+7

Explanation:

MnO41-

it is the same as Mn04 = -1

as generally known that the oxidation number of oxygen is -2, you'll insert -2 in the equation ie

Mn (-2 ×4) = -1

Mn (-8) =-1

add 8 to both sides

Mn -8+8 = -1+8

Mn = -1+8

Mn = +7
