The video tutorial explains how to determine the oxidation numbers for each element in the hydronium ion (H3O+). It starts by introducing the rules for finding oxidation numbers, focusing on hydrogen and oxygen. Hydrogen, when bonded to a non-metal like oxygen, has an oxidation number of +1. Oxygen typically has an oxidation number of -2. The tutorial demonstrates how these oxidation numbers add up to match the ion's charge, which is +1 for H3O+. The video concludes by verifying the calculations and confirming the correct oxidation numbers for the hydronium ion.
