Example: Sodium chloride, lead bromide, sodium hydroxide, nitric acid, sulphuric acid, and hydrochloric acid. [0.5 Mark]

Weak electrolyte: The substances that partially dissociate into ions in their aqueous solution or molten state are the weak electrolytes. [1 Mark] They contain ions as well as molecules in their solution. [0.5 Mark]
