Question

Problems:
1. Find the oxidation number of Mn in
KMnO4
k=+1,Mn=x,o=-2
+1+x-8=0
x-7=0
x=+7​

Answer 1

Answer:

yes you are absolutely correct Oxidation n umber  of Mn =+7

Explanation:

-To determine the oxidation state of an atom, we will consider it as 'X'.

- So to calculate the oxidation state of manganese in KMnO₄

, we will consider the oxidation state of manganese as 'X'.

-We know that the oxidation state of potassium and oxygen are +1 & -2.

-So, the equation will become:

+1 + x - 8 = 0⇒x = +7

-Hence, the oxidation of Mn is +7.
