2  The ability to dissolve or break down into its component ions in a liquid  Example:  NaCl is soluble  Completely dissolves in water  AgCl is insoluble  Stays a solid in water

3  Li, Na, K, NH 4, NO 3, C 2 H 3 O 2 are all soluble  Cl, Br, and I are soluble except when paired with Ag, Cu, Hg 2, Ni, and Pb  SO 4 is soluble except with Ag, Fe, Sr, Ba, Pb, or Ca  OH, S, CO 3, PO 4 are insoluble except when paired with Li, Na, K, NH 4

4  Determine whether each of the follow compounds is soluble or insoluble:  AgBr  Insoluble – Br is normally soluble but not when its with Ag  CaCl 2  Soluble  Pb(NO 3 ) 2  Soluble – NO 3 is always soluble  NH 4 Cl  Soluble - NH 4 and Cl are both soluble

5  A reaction in which a solid is formed upon mixing two aqueous solutions  Example:  Potassium Iodide + Lead Nitrate 2 KI (aq) + Pb(NO 3 ) 2 (aq) -> 2 KNO 3 (aq) + PbI 2 (s)

6  Write an equation for the precipitation reaction that occurs (if any) when solutions of sodium carbonate and copper (II) chloride are mixed.  Write an equation for the precipitation reaction that occurs (if any) when solutions of lithium nitrate and sodium sulfate are mixed. Na 2 CO 3 (aq) + CuCl 2 (aq) -> LiNO 3 (aq) + Na 2 SO 4 (aq) ->

7  Molecular Formula  An equation that shows the complete neutral formula for every compound  Complete Ionic Equation  An equation that shows the reactants and products as they are present in solution AgNO 3 (aq) + NaCl (aq) -> AgCl (s) + NaNO 3 (aq) Ag + (aq) + NO 3 - (aq) + Na + (aq) + Cl - (aq) -> AgCl (s) + Na + (aq) + NO 3 - (aq)

8  Spectator Ions  Ions that are present on both the reactant and product side.  They do not participate in the reaction  Net Ionic Equation  An equation that eliminates the spectator ions and shows only the elements or compounds that are participating Ag + (aq) + NO 3 - (aq) + Na + (aq) + Cl - (aq) -> AgCl (s) + Na + (aq) + NO 3 - (aq) Ag + (aq) + Cl - (aq) -> AgCl (s)

9  Consider the following reaction:  What is the complete ionic equation?  Which ions are the spectators?  What is the net ionic equation? HCl (aq) + NaOH (aq) -> H 2 O (l) + NaCl (aq)
