ACIDS, BASES, AND BUFFERS
o Re-emphasize solubility rules
o 6 strong acids and 9 strong bases; re emphasize
o Arrhenius and Bronsted Lowery acids and bases; conjugate acid base pairs
o Ka and Kb, the significance of Ka and Kb values on acid/base strength
o Acid strengthKa and Kb
Stronger acidsīƒ  weaker conjugate bases and vice versa
Acid strength: strong acid, weak acid, water, conjugates of strong bases
Relate acid strength to structure
o Autoionization and pH
Formulas
Significant digits
o pH of strong acids and bases
mixtures of two strong acids or two strong bases
mixtures of a strong acid and a weak acid or a strong base and a weak base
o pH of weak acids and bases
% ionization
o polyprotic acids
stepwise dissociation
special case H2SO4
o acid base properties of salts (chart)
o Common ion effect/buffers (worksheet that goes through all of the scenarios)
o Titrations- titration problem w/ graph
o Indicators
Not a lot of detail- just that indicators are weak acids and you want to choose an
indicator whose pKa is close to the pH at the equivalence point in order to get a color
change
