Oxidation states.

Today I was told that an H+ ion has an oxidation state +1... This is physically impossible right?

Also; how can H+ + H + O form water? ( disregard the fact that H and O aren't diatomic )

The molecule would be positively charged and there would only be 1 lone pair - it would also be a radical...

Thanks.
Nope. The Hydrogen atom forms a H+ ion when it loses it's electron. I don't really know how else to put that... When H+H+O form water, the Oxygen atom goes to the -2 oxidation state, taking one electron from each hydrogen to satisfy the 8 electrons it needs in it's valence shell, and giving both hydrogens a +1 charge. Hope that helps a bit!
