In Partial Defense of Calculating Titration Curves Stephen J. Hawkes
Calculating a titration curve is an unnecessarily complicated method of explaining how a buffer works, and equilibrium calculations are grossly over-emphasized in chemistry teaching.

In Partial Defense of Calculating Titration Curves Daniel C. Harris
There are more important subjects than calculating titration curves for a student whose only formal exposure to analytical chemistry will be an introductory course and whose primary interest is likely to be outside of chemistry (such as the life sciences).

Flame Emission Spectrometry in General Chemistry Labs: Solubility Product (Ksp) of Potassium Hydrogen Phthalate Frazier W. Nyasulu, William Cusworth III, David Lindquist, and John Mackin
In this general chemistry laboratory, flame emission spectrometry is used to determine the potassium ion concentration in saturated solutions of potassium hydrogen phthalate. From these data the solubility products, the Gibbs free energies of solution, the standard enthalpy of solution, and the standard entropy of solution are calculated.

Titration of a Solid Acid Monitored By X-Ray Diffraction Keenan E. Dungey and Paul Epstein
Presents a solid-state laboratory in which students react fixed amounts of zirconium phosphate with increasing equivalents of NaOH(aq). From X-ray diffraction patterns, students calculate the interplanar spacings before and after the reaction. The spacings increase until the molar equivalence point is reached, indicating incorporation of the sodium ion into the crystal.

A Closer Look at AcidBase Olfactory Titrations Kerry Neppel, Maria T. Oliver-Hoyo, Connie Queen, and Nicole Reed
This laboratory experiment uses the sense of smell to determine end points of acidbase titrations. Olfactory indicators include garlic, onions, and vanillin. Results show that garlic and vanillin gave the most accurate results when calculated NaOH molarities were compared to the standardized values. These olfactory indicators in acidbase titrations gave consistent results when tested by a diverse student population. The preparation times, cost, and safety issues are comparable to traditional titration experiments.

A Laser-Pointer-Based Spectrometer for Endpoint Detection of EDTA Titrations Christopher E. Dahm, James W. Hall, and Brian E. Mattioni
A simple laser-pointer-based spectrometer has been developed for endpoint detection of EDTA titrations of magnesium and calcium. This spectrometer was built to decrease the uncertainty in determining the endpoint of titrations performed with a Calmagite indicator. With a photoresistor as the detector, and with the aid of a voltage-divider circuit, the quantity of light being absorbed can be followed with a simple pHvoltmeter. Students determine the endpoint by graphing the data and applying simple mathematics. BeerLambert studies with the spectrometer also show excellent agreement for a given set of solutions.

This article provides a method to quantitatively determine the amount of both citric and ascorbic acid in a given sample of a powdered drink mix. The total moles of acid in the sample are determined by titration with sodium hydroxide. Moles of ascorbic acid are determined by titration with potassium iodate.

Instructions for the preparation of a Ag/AgCl "reference"-type electrode that uses a gel-type matrix are given. In addition, construction steps are provided for a very sturdy Pt-nichrome "inert" electrode, which can be used many times. Together, these two electrodes, along with a multivoltmeter, have been used successfully to determine the percent of iron in Fe(NH4)2(SO4)2 and in Fe2O2 unknowns purchased commercially.
