Description

The conductivity of a solution is concentration-dependent. A distinction is drawn between strong and weak electrolytes. While strong electrolytes are completely dissociated, the dissociation of weak electrolytes is highly concentration-dependent. In experiment C4.4.1.4, this behaviour is investigated in potassium chloride and acetic acid, and among other things the equivalent conductivity is determined.
