Chemistry
Differentiate between the terms strong electrolyte and weak electrolyte. (stating any two differences)
Answer
| Strong electrolytes | Weak electrolytes |
|---|---|
| They are electrolytes which allow a large amount of electricity to flow through them and hence are good conductors of electricity. | They are electrolytes which allow small amount of electricity to flow through them and hence are poor conductors of electricity. |
| They are almost completely dissociated in fused or aqueous solution state. | They are partially dissociated in fused or aqueous soln. state. |
