Tinture of iodine is simply iodine dissolved in alcohol. I don't understand your question.

The iodide is addded to better dissolve the iodine.
One can form I3- out of I2 and I- without a real redoxreaction. I3- has similar oxidative behaviour (and thus anticeptic properties) as I2.
You can neutralise it (and it's brown color) with sodium thiosulfate.
