Chapter 2: Q4.70P (page 40)

Give the oxidation number of manganese in the following:

aMnO42-bMn2O3cKMnO4

Short Answer

Expert verified

You need to provide the oxidation no of manganese for the given compounds.

Step by step solution

01

Oxidation state of manganese in MnO42-

Oxidation state of Oxygen is -2.

Let, oxidation state of manganese in MnO42-is x.

No you can write,

x+4-2=-2x=+6

Hence, oxidation state of manganese in MnO42-is +6.

02

Oxidation state of manganese in Mn2O3

Oxidation state of Oxygen is -2.

Let, oxidation state of manganese in Mn2O3is y.

No you can write,

2y+3-2=02y=+6y=+3

Hence, oxidation state of manganese in Mn2O3is +3.

03

Oxidation state of manganese in KMnO4

Oxidation state of Potassium is +1.

Oxidation state of Oxygen is -2.

Let, oxidation state of manganese in KMnO4is z.

No you can write,

+1+z+4-2=0z=+7

Hence, oxidation state of manganese in KMnO4is +7.
