Description

Liquids can also conduct electricity. A basic requirement for this is the presence of charged particles (ions), e.g. salts dissolved in water. In experiment C4.4.1.7 different liquids and solutions are examined for their conductivity. Solutions that can conduct the electric current are called electrolytes. In the additional part, strong electrolytes are distinguished from weak electrolytes.
