Answer
| Electricity flow through Nickel wire (metal) | Electricity flow through Nickel Sulphate Solution (electrolyte) |
|---|---|
| It is due to the flow of electrons which have negligible mass | It is due to the flow of ions which are denser compared to electrons. |
| There is no decomposition of parent metal and thus the chemical properties of the metal are intact. | There is decomposition of the electrolytic solution and thus the chemical properties of electrolyte are altered. |
| Good conductor of electricity in solid and in molten state. | Good conductors of electricity in aqueous solution or molten state but not in solid state. |
| During conduction, there is no transfer of matter. | During conduction there is transfer of ions. |
| The flow of electricity only produces heat energy and no new products are formed. | The flow of electricity decomposes nickel sulphate solution and new product — Nickel is formed. |
