concentration of ions of a sparingly soluble salt in water OTHER than at equilibrium is called the IONIC PRODUCT Example 1. AgCl [pic] Ag+ + Cl- Ksp = [Ag+][Cl-] Example 2 Cu(OH)2 [pic] Cu2+ + 2OH- Ksp = [Cu2+][OH-]2 Checkpoint A Write the Ksp expressions for the sparingly soluble salts below a. AgF b. HgCl2 c.

exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions present in the solution but
