The extraction of pure copper is expensive. give one reason why

Option (b) is the correct answer.

Explanation:

A solution in which solute particles completely dissociate into ions in a solvent is known as a strong electrolyte.

Whereas a solution in which solute particles partially dissociate into ions is known as a weak electrolyte.

A strong base is defined as a base that dissociates completely when dissolved in a polar solvent. On the other hand, a weak base is defined as a base that barely or partially dissociates into ions when dissolved in a solvent.

Similarly, strong acids dissociate completely into a solution and weak acids dissociate partially in a solution.

Therefore, strong bases are also strong electrolytes and weak bases are also weak electrolytes.

Thus, we can conclude that the difference between a strong and weak base is that strong bases are strong electrolytes and are completely ionized in solution. weak bases are weak electrolytes and are only partially ionized in solution.
