Oxidation State and Number

Is there any difference between oxidation state and number?

What are oxidation state and number of peroxydisulphuric acid ?

Oxidation state (with associated number) == oxidation number.

manzil_zaheer - 5-7-2006 at 09:12

what is associated number? please specify

Kindly explain difference with example.

What is the oxidation number and state of H2S4O6

manzil_zaheer - 5-7-2006 at 09:24

H2S4O6 means:

O O
|| ||
H -- O -- S -- S -- S -- S -- O -- H
|| ||
O O

Please tell both oxidation number and state for each element please.

manzil_zaheer - 5-7-2006 at 09:30

Sorry

.................O O
|| ||
H -- O -- S -- S -- S -- S -- O -- H

O O

HOW DO I DRAW THE STRUCTURE?

THE OXYGENS ON TOP AND BOTTOM ARE BONDED TO SULPHER 1 AND 4

What are you trying to draw?
Peroxodisulphuric acid is H2S2O8
The structure contains an O-O bond but no S-S bonds.

Peroxydisulphiric acid (H2S2O8) has sulphur in the +6 oxidation state, hydrogen in the +1 oxidation state, the two O's between the two S-atoms are in the -1 oxidation state and all other oxygens are in the -2 oxidation state.

The structure of this chem is H-O-S(=O2)-O-O-S(=O2)-O-H

With -S(=O2)- I mean an S, with an oxygen above and below, double bonded.

What is the oxidation number?

Ok we can use also peroxydisulphuric acid, what is the oxidation state and number of oxygen

12AX7 - 7-7-2006 at 13:50

WTF?

He just told you!!!

manzil_zaheer - 14-7-2006 at 09:28

i mean is there any difference in the oxidation state and number?

Please explain with the example of peroxydisulphuric acid

Given the oxidation state S of an atom, you can find the oxidation number as follows:

Construct the function F(z) = S / ((z - S) * 2 * pi * i) in the complex plane.

Then the oxidation number ON can be written as

ON = ∫ﮯ F(z)dz, where ∫ﮯ stands for the closed path integral along the Jordan curve with winding number 1 around the pole S of the function F(z).


There also is another way to compute ON.

ON = S :D
