Then, he shows students how to use the base dissociation constant, also known as Kb, to determine the pOH and pH for a weak base, while also calculating percent dissociation. He discusses the relationship between Ka and Kb, then shows the relationship between the strength of a weak acid and the strength of its conjugate base. He also shows how students can predict whether an ionic compound, sometimes called a salt, will be acidic, basic, or neutral in solution. 00:00 Introduction 00:41 Recognizing Weak Bases 01:58 Practice Problem No 1 06:56 Practice Problem No 2 09:40 Relationship Between Ka and Kb 10:41 Practice Problem No 3 13:14 Practice Problem No 4 16:30 Ionic Salts - Acidic or Basic? 19:46 Conclusion
