In Episode 5 of the Shedding Light on Acids and Bases series, Advanced Acid-Base Chemistry, we take a deeper look at pH and explain how the numbers on the pH scale are actually related to the number of H+ or OH- ions present in an acid or a base. We then descend even deeper down-to the atomic level-to explain what actually happens when acids react with bases and what actually happens when acids react with metals. We introduce students to ionic equations and to the role (or lack thereof) of spectator ions in many chemical reactions. This episode can be thought of as an extension to middle school acid-base chemistry or as an introduction to senior school acid-base chemistry.
