What is the oxidation number of in KIO4?

Answer 1

+1 for K

-2 for each O

+7 for I

Answer 2

7

Answer 3

Oxygen, is, as always, -2, and K is, as always, +1. Since the molecule has to be electrically neutral, you have to solve for x in the equation -2+1+x=0.

Yay for simple algebra :)

x clearly equals +1, so the oxidation for I is +1.

I probably don't have to tell you that is not the usual oxidation number of iodine, which has an oxidation number of -1.

Answer 4

+1 for potassium, +1 for Iodine, -2 for oxygen.

here iodine is not as iodide.

Answer 5

KIO

1+x+1=0

2+x=0

X= -2

Answer 6

+7
