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 characteristic curve of current against voltage of an electrolytic bath containing copper sulphate solution and having copper electrodes is measured. Visible changes in the electrodes and the bath are observed.
Tasks
The electrical conductivity is not only dependent on the type and concentration of the electrolytes, but also on other parameters of state. For example, increasing temperature is mostly accompanied by an increase in conductivity, which can be attributed to the expon ...
