  1. Strength of Acids/Bases 3. Strong vs Weak Acid/Base completely partially ionize ionize

  2. a. Common Strong Acids

  3. Common Strong Bases • All Group I & II A Metal Hydroxides

  4. D. Solution Reactions • 1. Neutralizations acidbasewatersalt HCl(aq) + NaOH(aq) H2O(l) + NaCl(aq) 2 HBr(aq) + Ba(OH)2(aq)  H2O(l) + BaBr(aq)

  5. 2. Net Ionic Equations • Only focus on the ions involved in the reaction • Determine what is left after the reaction • No spectator ions • Only break apart the STRONG ELECTROLYTES --- Use Solubility Rules!!!!!!

  6. Example (from WS #5) What are the Products?? (NH4)2S(aq) + FeCl3(aq) NH4Cl + Fe2S3

  7. Example (from WS #5) What is the Equation? (NH4)2S(aq) + FeCl3(aq) (NH4)2S(aq) + FeCl3(aq) NH4Cl + Fe2S3

  8. Example (from WS #5) (NH4)2S(aq) + FeCl3(aq) 3 (NH4)2S(aq) + 2 FeCl3(aq) 6 NH4Cl + Fe2S3 BALANCE

  9. Example (from WS #5) USE SOLUBILITY CHART (NH4)2S(aq) + FeCl3(aq) 3 (NH4)2S(aq) + 2 FeCl3(aq) 6 NH4Cl(aq) + Fe2S3(s)

  10. Example (from WS #5) Eliminate Spectators (NH4)2S(aq) + FeCl3(aq) 3 (NH4)2S(aq) + 2 FeCl3(aq) 6NH4Cl(aq) + Fe2S3(s)

  11. Example (from WS #5) What is left??? (NH4)2S(aq) + FeCl3(aq) 3 (NH4)2S(aq) + 2 FeCl3(aq) 6NH4Cl(aq) + Fe2S3(s) 3 S-2(aq) + 2 Fe+3(aq) Fe2S3(s) NET IONIC EQN: 2 Fe+3(aq) + 3 S-2(aq) Fe2S3(s)
