Presentation Transcript

  1. Acid-Base reactions CH3CO2H(aq) + NaOH(aq)  1. CH3CO2H2+(aq) + NaO(aq) 2. CH3CO2-(aq) + H2O(l) + Na+(aq) 3. CH4(g) + CO2(g) + H2O(l)

  2. Acid-Base reactions HCN(aq) + NH3(aq)  1. NH4+(aq) + CN-(aq) 2. H2CN+(aq) + NH2-(aq) 3. C2N2(s) + 3 H2(g)

  3. Acid-Base Reactions:Find the hidden bases Thing to know: Anions of weak acids are bases. Example: CH3COOH = weak acid CH3COO- therefore = weak base HCN = weak acid CN- = weak base H3PO4 = weak acid PO43- = weak base

  4. Return to Acid-Base Reactions:Find the hidden bases HCl + NaCN  ? HCl + AlPO4 ? HCl + CaC2O4 ?

  5. Precipitation Reactions Solubility of Ionic Compounds dissolving

  6. To Determine Solubility: 1. identify the two ions 2. soluble ions with no “exceptions” never form precipitates 3. use listing under soluble/insoluble, but check to see if it’s an exception

  7. Examples Soluble or Insoluble? • NaNO3 • FeCl3 • Fe(OH)3 • BaSO4 • AgNO3 • AgCl

  8. More Examples Soluble or Insoluble? • K3PO4 • Fe3(PO4)2 • PbCl2 • FeSO4 • (NH4)2S • PbS

  9. PRS Example 1 Which of the following is soluble? • AlPO4 • PbBr2 • Al(OH)3 • FeSO4

  10. PRS Example 2 Which of the following is insoluble? • Al(NO3)3 • PbC2O4 • NaOH • FeF3

  11. Precipitation ReactionsNet Ionic Equations Pb(NO3)2 + K2CrO4 ? Pb(NO3)2 + KI  ? BaCl2 + KNO3 

  12. Gas Forming Reactions 2 H+ + CO32- CO2(g) + H2O(l) 2 H+ + SO32- SO2(g) + H2O(l) 2 H+ + M  H2(g) + M2+(aq) M = metal, like Mg or Fe
