Concept introduction:
Electrolyte:
- The chemical compound, which dissociate to give ions in water and conduct electricity is called electrolyte.
- The weak electrolyte is not completely dissociated to give ions in water so the conductivity is less than the strong electrolyte.
- The chemical compound, which is completely dissociate to give the ions in water and conduct the electricity is called strong electrolyte.
- The chemical compound, which is dissolved in water but is does not conducts the electricity is called non electrolyte.
