7.5.1.2 Weak Electrolytes
The electrolytes which ionize to a small extent when dissolved in water and could not produce more ions
are called weak electrolytes. Acetic acid (CH3COOH) and Ca(OH)2 when dissolved in water, ionize
to a small extent and are good examples of weak electrolytes. Weak electrolytes do not ionize
completely. For example, ionization of acetic acid in water produces less ions:

As a result the weak electrolyte is a poor conductor of electricity.

7.5.1.3 Non-Electrolytes

The substances, which do not ionize in their aqueous solutions and do not allow the current to pass
through their solutions, are called non-electrolytes. For example, sugar solution and benzene are
non-electrolytes.
