  1. Acids and Bases And Salts

  2. Acidic Solution

  3. Basic Solution

  4. Acidic Solution = H+ in solution HBr HNO2 NH4+

  5. Basic Solution = OH- in solution KOH NH3 F-

  6. Acidic, Basic, or Neutral? NO2- NO3- Na+ ClO2-

  7. Acidic, Basic, or Neutral? • An anion that is the CB of a {} is {}. • A cationthat is the CA of a {}is {}.

  8. salt hydro- -lysis any ionic cmpd that is not an acid or a base (cation is not H+. anion is not OH-) water to break apart Salt Hydrolysis

  9. Salt Hydrolysis Consider BOTH ions to determine identity of salt. (ex) KC2H3O2

  10. Salt Hydrolysis Shortcut: Look at parent acid and parent base. NH4Cl

  11. Salt Hydrolysis NaCN CaBr2

  12. Salt Hydrolysis (NH4)2SO3 If Ka(cation) = Kb(anion) If Ka (cation) > Kb (anion) If Ka (cation) < Kb (anion) Neutral salt Acidic salt Basic salt

  13. What is the pH of 0.10M NaOCl?

  14. What is the pH of 0.20M hydrazinium chloride, N2H5Cl? Kb(hydrazine, N2H4) = 1.7 x 10-6

  15. Is 0.20M NH4F acidic, basic or neutral? Justify your answer.
