Electrolytes and its Types
Electrolytes:
A compound that conduct electricity in molten (fused) or aqueous (solution) state and which simultaneously undergoes decomposition (breaking into ions), with the passage of an electric current through it, is an electrolyte. We classify electrolytes as strong electrolytes and weak electrolytes. This is done on the basis of the extent to which the electrolyte breaks into ions.
1. Strong Electrolytes:
These are the electrolytes that ionize completely to form free mobile ions in the solution. A large number of free mobile ions are available, in them, to conduct electricity. For eg. .
2. Week Electrolytes:
These are the electrolytes that ionize only partially to form free mobile ions. Only a small number of free mobile ions are available, in them, to conduct electricity. For eg. etc.

8thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
