Principle
Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanicor similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlle ...
The pH value (a measure of the concentration of hydrogen ions) in running waters depends on the geological conditions, the pollution load that is caused by agricultural production, and on plant activities. This experiment shows how the pH value of a ...
This experiment shows how the salt that is washed out of an abandoned potassium rock pile drastically increases the salinity of a watercourse, as well as how the salinity decreases only slightly further downstream, and how the salinity can still be me ...
A visit to a water treatment plant reveals some fascinating procedures and purification methods. We will not merely be concerned with interesting impressions, but instead we will increase our understanding for microbiological processes by measuring t ...
Determination of conductivity.

What you can learn about
In this experiment, acid rain is to be artificially prepared by passing gases such as SO2, NO2 and Co2 through water.
