प्रश्न
Differentiate between the terms strong electrolyte and weak electrolyte (stating any two differences)
उत्तर
| Strong Electrolytes | Weak Electrolytes |
| Electrolytes which allow a large amount of electricity to flow through them. | Electrolytes which allow small amounts of electricity to flow through them. |
| These are good conductors of electricity. | These are poor conductors of electricity. |
| These almost completely dissociate in the fused or aqueous solution state. | These are partially dissociated in the fused or aqueous solution state. |
| These solutions contain only free mobile ions. | These solutions contain ions as well as molecules. |
