What mass of lead sulfate is formed in a lead–acid storage battery when 1.00 g of Pb undergoes oxidation?
CHAPTER 17: ACID-BASE AND SOLUBILITIY EQUILIBRIA GENERAL CHEMISTRY II This general outline is meant as a supplement to the General Chemistry II (1312) course taught at the University of Texas at Dallas and should not be taken as a standalone study guide for the overall curriculum. However, I do hope that this broad summary of the textbook helps you all in becoming successful undergraduate students here at UTD. Justin Sequerra, “Chemistry is the study of matter. But I prefer to see it as the study of change.” – Walter White, Breaking Bad 1 ACID-BASE AND SOLUBILITY EQUILIBRIA 17.1 THE COMMON ION EFFECT Up to now: Have only dealt w/ solutions w/ only 1 solute Now: We get to add another Think of these questions as Le Chatelier’s principle (Ch. 15 Recap: Any change in equilibrium results in the system undergoing a change to reduce the stress) but w/ more focus on the addition of reactants or products One must also understand acidbase properties of salt solutions (Ch. 16 Recap: Dissolve salt completely (ex: NaCl) and look at the ions (Na+ and Cl) and decide how they may affect the solutions equilibrium and pH (if they do)) Weak electrolyte (weak base or acid) dissolves in solution to form ionssalt dissolved later in solution may also have the same ion(s) (Common Ion Effect: Sidebar Definition) Addition of these “common” salts SUPPRESSES the ionization of the weak electrolyte (Shifts the Equilibrium to the left
