Chapter 16 Objectives (Part II) (Aqueous Ionic Equilibrium) Spring 2084 1. There is some solubility for even the ‘insoluble’ salts such as BaSO 4 and AgCl which the solubility rules label as ‘insoluble’. a) There is an equilibrium constant called K sp (solubility product constant) for such salts. BaSO 4 + 2 ) aq ( Ba + - 2 ) aq ( 4 SO K sp = [Ba 2+ ] [ 2 4 SO ] = 1.1 × 10 -10 AgCl (s) + ) aq ( Ag + - ) aq ( Cl K sp = [Ag + ] [Cl¯] = 1.5 × 10 -10 Cd 3 (PO 4 ) 2(s) 3 + 2 ) aq ( Cd + 2 - 3 ) aq ( 4 PO K sp = [Cd 2+ ] 3 [ - 3 4 PO ] 2 b) In each case, we let the molar solubility be s. The solid has a constant concentration and does not appear in the expression for K sp . Example 1: What is the K sp value for a salt MX 2(s) if its molar solubility is 1.00 × 10 -4 M? Given: MX 2(s) + 2 ) aq ( M + 2 - ) aq ( X . Example 2: What are the generic forms of the K sp expression for the following types of salts? 1:1
