A collective-effort, guided-inquiry laboratory investigation was developed for the second-semester general chemistry laboratory for the purpose of increasing student conceptual understanding of equilibrium and speciation phenomena. This investigation required students to employ the chemical indicator phenol red in phosphate buffer solution, computer interfaced pH probes, and visible spectrophotometers. Through a combination of potentiometric and visible absorption measurements, the students determined the pH conditions that alter equilibrium concentrations of multiple species (colored and transparent) in solution.

Making Usable, Quality Opaque or Transparent Soap  Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Introduction to Photolithography: Preparation of Microscale Polymer Silhouettes  Kimberly L. Berkowski, Kyle N. Plunkett, Qing Yu, and Jeffrey S. Moore
In this experiment, a glass microscope slide acts as the microchip. Students can pattern this "microchip" by layering negative photoresist on the slide using a solution containing monomer, crosslinker, photoinitiator, and dye. The students then cover the photoresist with a photomask, which is the negative of a computer-generated image or text printed on transparency film, and illuminate it with UV light. The photoresist in the exposed area polymerizes into a polymer network with a shape dictated by the photomask. The versatility of this technique is exemplified by allowing each student to fabricate virtually any shape imaginable, including his or her silhouette.

The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product.

Equilibrium Constants and Water Activity  David Keeports
General chemistry instructors are faced with a dilemma when introducing the topic of equilibrium constants: These constants are correctly written in terms of activities, yet activity is a complex topic better treated rigorously in a physical chemistry course than superficially in a general chemistry course. Thus, to introduce equilibrium calculations, it is necessary to use approximate forms for equilibrium constants. However, I find that some commonly used textbooks provide incorrect arguments leading to approximate equilibrium constants for aqueous reactions.

Unified Approximations: A New Approach for Monoprotic Weak Acid–Base Equilibria  Harry L. Pardue, Ihab N. Odeh, and Teweldemedhin M. Tesfai
This article describes a new approach to approximate calculations for monoprotic acidbase equilibria in otherwise pure water. The new approach, identified herein as unified approximations, uses a simple decision criterion to select between situations that should be treated as deprotonation and protonation reactions. The remaining treatment takes account of changes in concentrations of conjugate acidbase pairs for all situations and ignores autoprotolysis only for situations for which the analytical concentration of either the conjugate acid or conjugate base will always be larger than zero.

The Preparation and Testing of a Common Emulsion and Personal Care Product: Lotion  Suzanne T. Mabrouk
First-year chemistry students can readily prepare lotion from the emulsification of deionized water, humectant, emulsifier, emollients, thickener, and preservative. Three different lotion formulations are prepared so that students can study the effects of different emulsifiers and emollients on the quality of the final product. The purpose of the ingredients is discussed.

Simple Experiments To Demonstrate Proton Flux in Pseudomonas after Alkaline or Acidic Stress  Gabriela Previtali, Walter Giordano, and Carlos E. Domenech
A laboratory experiment to ascertain the bacterial response to the stress produced by suspension in different pH solutions has been developed. This laboratory experiment has the pedagogical advantage of giving chemistry students experience with the application of various pH levels to a biological system and enables the students to expand their understanding of pH to mean more than a strictly chemical concept.

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.

Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives.

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.

Do pH in Your Head  Addison Ault
Every aqueous solution has a pH. Two factors determine this pH: the acidic or basic strength of the solute, and its concentration. When you use pKa values to express acidic and basic strength you can easily estimate the approximate pH of many aqueous solutions of acids, bases, and their salts and their buffers.

Why Not Replace pH and pOH by Just One Real Acidity Grade, AG?  Henk van Lubeck
The disadvantages of pH and pOH disappear after replacing them with AG, the acidity grade: AG = log [H+]/[OH-]. AG of neutral solutions equals 0 at all temperatures, whereas AG of acidic solutions is positive and of alkaline solutions, negative. AG offers some other minor advantages as well.

The Ammonia Smoke Fountain: An Interesting Thermodynamic Adventure  M. Dale Alexander
The ammonia smoke fountain demonstration utilizes a modification of the apparatus used in the standard ammonia fountain. The modification allows for the introduction of hydrogen chloride gas into a flask of ammonia rather than water. The flow rate of hydrogen chloride gas into the flask in the smoke fountain is not constant, but periodic; that is, the smoke puffs from the end of the tube. This unexpected behavior elicits an interesting thermodynamic explanation.

The Fizz Keeper, a Case Study in Chemical Education, Equilibrium, and Kinetics  Reed Howald
The chemistry of the loss of carbonation from carbonated beverages on storage is considered. Increasing the pressure of CO2(g) will restore carbonation, but an increase in pressure adding air should not affect the equilibria. It can and does, however, affect the kinetics-the rate at which a new equilibrium is established. Thus the Fizz Keeper is effective for storage of resealed pop containers for hours, but not for periods of weeks or months.
