8 weeks · About 6 hours per week

Week 1

Quantitative analysis: titrimetry, gravimetry, and spectrophotometry & Data treatment, error analysis, and graphical methods

  • Derive the titration error equations for strong acid–strong base, weak acid, and redox titrations, and compute the theoretical titration curve for three assigned systems by hand.

  • Calculate the equivalence-point pH for weak acid and weak base titrations from Ka/Kb and concentration, verifying each result against a mass-balance check.

  • Distinguish random from systematic error in a set of 20 hypothetical burette readings, and compute mean, standard deviation, and 95% confidence interval for each subset.

  • Propagate uncertainty through a gravimetric calculation (mass of precipitate to molarity of analyte) using both the quadrature and worst-case methods, and compare the outcomes.

  • Set up a spreadsheet that plots a titration curve from raw volume–pH data and marks the first and second derivative endpoints.

Your checkpoint

Week 2

Quantitative analysis: titrimetry, gravimetry, and spectrophotometry & Data treatment, error analysis, and graphical methods

  • Solve five gravimetric problems requiring correction for solubility loss, coprecipitation, and ignition stoichiometry, and justify each correction numerically.

  • Derive the Beer–Lambert relationship from first principles and calculate the concentration of an unknown from a five-point calibration using least-squares regression.

  • Construct a calibration curve by hand from provided absorbance data, compute the slope, intercept, and R², and interpret whether the intercept is statistically different from zero.

  • Derive integrated rate laws for zero-, first-, and second-order reactions and determine reaction order from three data sets using graphical and half-life methods.

  • Determine the number of ions and the transport number from conductivity measurements on a dilute electrolyte series.

  • Predict the geometry and magnetic moment of a set of coordination complexes using crystal-field theory, and identify which cases require ligand-field or Jahn–Teller arguments.
