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

The oxidation number of iodine (I) in KIO4 is +7. This is because the oxidation number of potassium (K) is +1, and the overall compound has to be neutral, so the sum of the oxidation numbers must equal zero.

Answer 5

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

here iodine is not as iodide.

Answer 6

KIO

1+x+1=0

2+x=0

X= -2

Answer 7

+7
