Whats the oxidation state of iodine in I₃^-?

[Hunter2]

One Iodine is -1 the other two  0. Same rule like in carbonhydrids. C-C is also 0.

For mathematics  in redox reaction how much is the value then for Iodine?

You should show your attempts at solving the question to receive help. This is a forum policy.

There is no real physical property that can be measured and that reflects oxidation state of atom. It is nothing unusual to get some strange values.

Sorry for not showing my attempt. The qns i ask here are either attepted and still cant be solved by myself or i have no idea at all, otherwise i wouldnt post qns which i havent thought about it for a very long time ald.

Could you explain more about carbohydrids? What are they are why can specific oxidation states be given to certain atoms instead of dividing the charge by the total number of atoms?

Lets have CH₄ then Carbon is -4 and the hydrogen each +1.

CH₃-CH₃ by law a C-C bond is 0, so each Carbon is -3

CH₃-CH₂-CH₃  -3,-2,-3, etc.

or
CH₃-COOH  -3, +3 and more examples.
