  1. Calculate the solubility of PbSO4 whoseKsp = 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. Balancing REDOX Reactions

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

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

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

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

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

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

  16. Balance Redox Rxns: • MnO4-1 + N2O3 • Mn+3 + N2O5 • in base

  17. Balance Redox Rxns: • HNO3 + Cu • N2O + Cu+2 • in acid

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

  19. Balance Redox Rxns: • MnO2 + P4 • Mn2O7 + PH3 • in acid

  20. Balance Redox Rxns: • FeCl2 + KNO3 • FeCl3 + KNO • in base

  21. Balance Redox Rxns: • SnF2 + KIO4 • KI + SnF4 • in acid

  22. Balance Redox Rxns: • IO3-1 + I-1 • I3-1 • in acid

  23. Balance Redox Rxns: • PbBr4 + K2O • PbBr2 + O2 • in acid

  24. Balance Redox Rxns: • Ca + VO4-3 • CaO + V+2 • in acid

  25. Balance Redox Rxns: • Fe(OH)3 + Cr(OH)4-1 • Fe(OH)2 + CrO4-2 • in base

  26. Balance Redox Rxns: • Ni(OH)2 + N2H4 • Ni + N2 • in base

  27. Balance Redox Rxns: • K3PO4 + Cr+2 • P2O3 + K2CrO3 • in acid

  28. Balance Redox Rxns: • H2SO4 + Cr+2 • SO + H2Cr2O7 • in acid

  29. Balance Redox Rxns: • PH3 + KMnO4 • P2O5 + Mn2O3 • in KOH
