Topics and Learning Outcomes
Acids and Bases
explain the advantages of the Bronsted-Lowry acid-base definition over the Arrhenius definition understand the relationships between pH, pOH, pK a , pK b and pK w predict qualitatively the excess species in weak conjugate acid-base pairs at a given pH calculate the pH, pOH, [H+ ] and [OH- ] for aqueous solutions of strong acids and bases predict qualitatively the relative acidities of strong acids calculate the pH, pOH, [H+ ] and [OH- ] for very diluite solutions of strong acids and bases calculate the pH, pOH, [H+ ] and [OH- ] for aqueous solutions of weak acids and bases calculate the pK a of a weak, monoprotic acid from the pH of its solution predict the sequence of strengths of acidities of weak, polyprotic acids predict qualitatively the pH of salt solutions calculate the pH of solutions of hydrated metal ions identify Lewis acids and bases explain the origin of buffering action calculate the pH change for addition of acid or base to a buffer choose an appropriate buffer for any pH value explain how to prepare a buffer solution explain the buffering action of Hs CO3 / HCO3 - in the blood explain how to perform an acid-base titration selection an indicator for the titration of any combination of acid and base predict the charge of an amino acid and its direction of migration in electrophoresis given its pI explain the origins of positive and negative charges on a protein predict qualitatively the change in solubility of a protein with changing pH given its pI
Solubility
convert between concentration units of molarity and ppm write solubility product expressions calculate K sp from solubility data calculate solubility from K sp calculate the effects of a common ion on solubility predict whether or not a precipitate will form at a given concentration of salt solutions explain why iron storage proteins are required for iron
