Question

Q.7 The Oxidation number of Mn in KMnO, is +7 True or False​

Answer 1

Answer:

True if you mean by KMnO4

Explanation:

K is always -1

and O is always -2 and -1 when it is a peroxide, so in this case your O is -2

so we form an equation, we let Mn = x

If your compound is KMnO4

1 + x + 4(-2) = 0 (because it is a neutral compound)

1 + x -8 = 0

x= +7 so it is correct

If your compound is KMnO ,

1 + x - 2 = O

x = +1

Your Mn suppose to be 1 so it will not be +7
