  1. Drill: Calculate the solubility of PbSO4Ksp = 2.0 x 10-14

  2. Review Drill&Check HW

  3. CHM II HW • Review PP-27 • Complete the attached assignment & turn it in tomorrow.

  4. Oxidation Reduction Reactions(REDOX)

  5. REDOX Reactions • Chemical reactions in which electrons are transferred

  6. Chemical Charge • A positive, neutral, or negative number assigned to a particle & determined by the difference between the # of protons & electrons

  7. Oxidation Number • The charge of a single atom

  8. Oxidation • The act of losing electrons • Oxidation number increases

  9. Reduction • The act of gaining electrons • Oxidation number decreases

  10. REDOX Fact • You cannot have oxidation without reduction or reduction without oxidation

  11. Oxidizing Agent • A substance that oxidizes another • The oxidizing agent will be reduced

  12. Reducing Agent • A substance that reduces another • The reducing agent will be oxidized

  13. Determine elements being: oxidized & reduced MnO4-1 + NH3 MnO2 + NO2-1

  14. Drill: determine ox # of each element: MnO4-1 + Fe Mn2O3 + FeO

  15. Balance the following in Acid: MnO4-1 + Fe Mn2O3 + FeO

  16. Balancing REDOX Reactions

  17. Balancing Redox Rxns • Determine all ox # • Determine elements being oxidized & reduced • Divide rxn into half-rxns • Balance half-rxns

  18. Balancing Half-Rxns • Balance redox elements • Balance ox # with e- • Balance e- between the two half-rxns

  19. Balancing Half-Rxns • Balance total charge with H+ or OH- • Balance H’s with water • Check balance with oxygen

  20. Balancing Redox Rxns 5) Add the two half-reactions • Cancel like substances from each side of the full reaction • Check work

  21. Drill: Determine Ox #: • MnO2 + Cl-1 • Mn+2 + Cl2 • in acid

  22. Balance Redox Rxn: • MnO2 + Cl-1 • Mn+2 + Cl2 • in acid
