Question

What is the oxidation state of potassium in ko2?

Answer 1

Heya,

KO2 in this the oxygen have (-1/2) oxidation state.
So,to find out oxidation state of K let us assume it as 'x', now,

x + 2(-1/2) = 0
x - 1 = 0
x = +1

So, by this we can see that oxidation State of potassium in KO2 is +1.

Hope this helps...:)

Answer 2

x-4=0
x=+4
is the o.s
