analytical chemistry

Recently, Anne Schmidt and I published an article together in the Journal of Chemical Education.¹ The article outlines a titration activity that students can carry out at home using only store-bought items. The objective of the activity is to determine the amount of Mg(OH)₂ in milk of magnesia.

I’d like to describe a very colorful system you can use to explore many facets of chemical equilibrium.

Are you up for trying an ambitious experiment that combines archeology, instrumental analysis, and a search for patterns in data? Then this activity might fit the bill! I came up with this activity after slipping into one of Kevin Braun’s presentations at the BCCE 2016 in Colorado.

How do you demonstrate the workings and effectiveness of buffers in your acid-base unit?

I was doing some kinetic experiments when I came across the V​itamin C Clock Reaction published in the Journal of Chemical Education¹.

Citric acid is a weak tricarboxylic organic acid. It is highly soluble in water and, once it dissolves in that, it shows weak acidity but a strongly acidic taste which affects sweetness and provides a fruity tartness for which it is widely used to complement fruit flavors in the food and beverage industry.
