Question

Predict the oxidation state of metal ion in the foll compounds
-

MnCl2​

Answer 1

Answer:

Consider the oxidation state of Mn as x.

The charges on Cl,O,H,K are −1,−2,+1,+1 respectively. Therefore, the oxidation states of Mn in its given compounds can be calculated as follows:

MnCl

2

→ x+(−2)=0 ⇒ x=+2

Mn(OH)

3

→x+(−3)=0⇒x=+3

MnO

2

→x+(−4)=0⇒x=+4

KMnO

4

→+1+x+(−8)=0⇒x=+7

Hence, option B is the correct answer of this question.
