Description

Liquids conduct electricity when ions are present. Salts should therefore conduct electricity when they are present in liquid form, i.e. as a melt. In experiment C4.4.1.8, a salt mixture is melted and its conductivity measured. We use a mixture of lithium chloride and potassium chloride because, due to the eutectic, it has a melting point of only 355 °C.
