The following observation has to be justified – “The electrical conductance of metallic copper decreases with increase in temperature but that of Copper sulfate solution increases with increase in temperature”. Concept Introduction: Metals are good conductors of electricity. Conductivity of metals is due to the movement of free electrons from one region to another region. Aqueous solution of ionic solids also conducts electricity. In aqueous solution, an ionic solid is completely dissociated and exist as individual ions . The movement of ions of opposite charges towards their respective electrodes generates electricity.
