On Thursday, November 10th 2016, in the morning the French and German students analyzed samples of tap water.
They had brought from their homes (Hardness,pH, conductivity, chlorides and sulphates).
After a well detiled explanation and a quick slide show to better understand the reactions, the students immediately went to the lab were they worked in pairs and were helped by two Italian students. Conductivity and pH test were completed thanks to their respective tools. Sulphates and chlorides verification were carried out by using their specific reactants.
Hardness test was a titration using EDTA, the students were able to check their waters hardness (hardness is a non-specific parameters that helps to understand how many ions can be found). The final results were put in a chart.
