Oxidation Numbers and Ions

The video tutorial explains how to find oxidation numbers for each element in the ion IO6^5-. It begins by discussing the general rule that oxidation numbers in an ion add up to the ion's charge. The tutorial then focuses on determining the oxidation number of iodine, given that oxygen is typically -2. By setting up an equation, the oxidation number of iodine is calculated to be +7. The video concludes with a summary of the process.
