Bromic Acid and Bromate Ions

The video tutorial explains how to derive the formula for bromic acid. It begins by identifying that acids typically start with hydrogen and that bromic acid contains three elements, indicating the presence of a polyatomic ion. The tutorial then details the process of using the stem 'brome' and the suffix 'ic' to determine the bromate ion, which is BrO3-. The video further explains how to balance the charges between hydrogen and the bromate ion to arrive at the formula HBrO3. The tutorial concludes with a recap of the steps taken to derive the formula.
