During the class we discover some mysteries of the water. In the first, theoretical part, we answer questions like: what is the structure of the water molecule, what biological significance it has, do people have impact on pH of water environments, what chemical components are responsible for hardness of water and if we can remove it. As the theory itself is not enough, the second part of the class is practical. Working in groups, we investigate salinity of water from different seas, measure pH or content of calcium and magnesium of fresh and seawater.
