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.

Quantitative Determination of Citric and Ascorbic Acid in Powdered Drink Mixes: A High School or General Chemistry Experiment  Samuella B. Sigmann and Dale E. Wheeler
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. Moles of citric acid are determined by difference.

Canadian Tire Money: An Analogy for Use When Discussing Weak Acid–Strong Base Titrations  Arthur M. Last
In this article, use is made of the practice of one well-known Canadian retail chain in returning to its customers a small percentage of an item's purchase price in the form of imitation bank notes that can subsequently be spent in the chain's stores. An analogy is drawn between this practice and the determination of the pKa of a weak acid by titrating it with a strong base, taking into account the hydrolysis of the anion produced.

Predicting Acid-Base Titration Curves without Calculations  Dennis W. Barnum
In this paper a qualitative and systematic method for sketching titration curves is presented. Even the more complex cases such as salts or polyprotic acids and bases are treated just as easily as simple monoprotic acids. Having students predict the shape of titration curves from known equilibrium constants helps to focus attention on the general principles without distraction by the mathematics.

A Unified Titration Formula  P. Glaister
In a number of standard titrations, a volume of a monoprotic base MOH at a specific concentration is added to a volume of a monoprotic acid HA at a specific concentrations. Four different types of titration are possible, depending on whether the acid and base are strong or weak. A single unifying formula covering all four cases has been determined.
