The video tutorial explains how to determine the oxidation states of elements in the hypo iodide ion (IO-). It begins by introducing the ion and its negative charge, then outlines the general rules for finding oxidation numbers. The tutorial demonstrates the calculation process, showing that oxygen typically has an oxidation number of -2, and solving for iodine's oxidation number using an equation. The video concludes by verifying the results and ensuring the calculations align with the ion's charge.
