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).

A Closer Look at AcidBase 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 acidbase 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 acidbase 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 pHvoltmeter. Students determine the endpoint by graphing the data and applying simple mathematics. BeerLambert studies with the spectrometer also show excellent agreement for a given set of solutions.
