AP Chem - we did two more salt pH, pKa, pKb, % ionization problems, going through the various permutations of knowns and unknowns; typically, these questions will use a little bait-and-switch: for basic salts, the Ka or pKa of the conjugate acid of the basic anion is usually given, for acidic salts, the Kb or pKb of the conjugate base of the acidic cation is usually given.
Here is a preliminary list of question types for your test next Tuesday:
• sparingly soluble salt equilibrium shifts
due to stresses (explain via kinetics, predict via Le Chat)
•conjugate acid-base pairs and predicting the favored side of rxn as eq. is reached given Ka, Kb, values
• pH, pOH calculation for strong acids and bases
• explanation of acid strength via bond polarity
 and bond strength and their causes (Zeff, etc.)
•weak acid eq, calcs pH, pKa,[HA]initial % ionization
•weak base eq pH, pOH, pKb,  [B]initial,  % ionization
•acidic ,basic salts
-causes/ reactions
•pH calcs of acid, basic salts  BHX, MA

Bio - we took the unit exam on regulation via the nervous system.
