Answer
| Electrical conductivity of copper sulphate solution | Electrical conductivity of copper metal |
|---|---|
| The flow of electricity takes place by flow of ions which are denser compared to electrons. | The flow of electricity takes place by flow of electrons which have negligible mass. |
| There is decomposition of the copper sulphate solution and thus the chemical properties of electrolyte are altered. | There is no decomposition of copper metal and thus the chemical properties of copper are intact. |
| Good conductors of electricity in aq. soln. or molten state but not in solid state. | Good conductor of electricity in solid and in molten state. |
| During conduction through copper sulphate solution, there is transfer of ions. | During conduction through copper metal, there is no transfer of matter. |
| The flow of electricity decomposes the electrolyte and new products are formed. | The flow of electricity only produces heat energy and no new products are formed. |
