16.6 Acidity and Basicity of Salts | General Chemistry

Chad provides a comprehensive lesson on the acidity and basicity of salts. Salts (aka ionic compounds) are composed of cations and anions. Cations, being positively charged, tend to act as Lewis acids (electron acceptors), whereas anions, being negatively charged, tend to act as Lewis bases. Knowing the strong acids and bases will be key to remembering which cations are not acidic and which anions are not basic. Once cations and anions are examined for acidity and basicity respectively, it can be determined whether or not a salt is acidic, basic, or neutral. The lesson is concluded by a demonstration of how to calculate the pH of a basic salt (from the Ka of the anion's conjugate acid) or an acidic salt (from the Kb of the cation's conjugate base). I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
