Perform calculations involving equilibria of weak acids, weak bases and buffers. e. Solve solution inventory problems for slightly soluble salts and complex ions. f. Analyze titration curves of weak, strong, and polyprotic acids and bases to determine concentrations and equilibrium constant values. g. Calculate the Gibbs free energy for reactions and interpret the relationships between entropy, enthalpy, temperature, and spontaneity. h. Relate free energy to equilibrium constants. i. Demonstrate understanding of standard reduction potentials in relationship to electrochemical cells. j. Calculate cell potentials to cells under non-standard conditions. k. Solve quantitative electrochemical problems. l. Identify the components of an electrolytic or galvanic cell. m. Explain colors of transition metal compounds in terms of ligand field theory. n. Classify substances on the basis of their chemical reactivities. o. Describe different types of isomerism in organic and inorganic compounds. p. Analyze and balance nuclear equations. q. Demonstrate an understanding of the concepts of fission, fusion, transmutation, and natural radioactive decay. r. Classify organic compounds on the basis of structure and functional groups. s.
