From Hackuarium

Lab Warming! June 2019


Who I am

I am a retired chemistry teacher from the Gymnase de Chamblandes in Pully-Lausanne. I was also the President of the Swiss Association of Natural Science Teachers. After initiating Swiss participation in the International Chemistry Olympiad (IChO) already thirty years ago, I am still glad to be active in this field.

Why I love Hackuarium

Because there is a great community and room enough to carry out simple chemistry experiments, any time I want, I am very glad to be a member of Hackuarium.

As a retired chemistry teacher, I cannot go any more to my former high school.

I need at least a small lab to develop the laboratory experiments required to take part to the olympic selection in Switzerland.

Current projects

I am trying to develop a simple experiment to be done by the candidates at the IChO that will happening July 2023 in Zurich with 300 students from all over the world. I am presently checking whether the concentration of salicylic acid can be measured in solution with simple equipment. For example by spectrophotometry with iron(III) in a mixture with two other acids.
