  1. Answers to Acids and Bases review questions not in book

  2. A. Self-ionization of water • Truth: • H2O + H2O  H3O+ + OH- • Convenient lie: • H2O  H+ + OH-

  3. B. Common Properties • See notes organizer that goes with power point from beginning of unit • Powerpoint is uploaded on my blog if you need review

  4. C. Predict products, write acid name • Be(IO3)2 (s) + H2(g), HIO3= iodic acid • 2Al(ClO4)3 (aq) + 3 H2, HClO4 (aq) = perchloric acid • NaF (aq) + CO2(g) + H2O(l), HF = hydrofluoric acid • SrSeO4(s) + H2O(l) + CO2(g), H2SeO4 = selenic acid • (NH4)2SO3(aq) OR NH4HSO3, H2SO3 = sulfurous acid • CaBr2 + H2O, HBr = hydrobromic acid

  5. F. Find pH of bases • To find pH of bases, first find the pOH, then subtract from 14 to get the pH. • To find the pOH, use neg log [OH-] • pH=13.40 • pH=11.48 (remember to double the molarity, since there are 2 OH- moles for each mole of Ba(OH)2

  6. G, H & I Titrations • 0.0671 M KOH • 0.329 M HNO3 • 30. mL
