Presentation Transcript

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

  2. Oxidation Reduction Reactions(REDOX)

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

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

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

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

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

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

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

  10. Drill: determine ox # of each element: __MnO4-1 + __Fe __Mn2O3 + __Fe+2

  11. Balancing REDOX Reactions

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

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

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

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

  16. Balance Redox Rxns: • MnO2 + Cl-1 • Mn+2 + Cl2 • in acid

  19. Balance Redox Rxns: • Cr2O7-2 + NH3 • Cr+3 + NO3-1 • in base

  20. Drill: Balance: • MnO4-1 + N2O3 • Mn+3 + N2O5 • in base

  21. Drill: Balance Rxns: • HNO3 + Cu • N2O + Cu+2

  22. Balance Redox Rxns: • SO2 + Pb(OH)2 • SO3 + Pb • in base
