Question

It is said that HClO₄ is a strong acid, whereas HClO₂ is a weak acid. What does this mean in terms of the extent to which the two substances are ionized in solution?

CramX · Accepted Answer

Step 1: I'll solve this problem step by step, explaining the difference between strong and weak acids in terms of their ionization.. Step 2: : Define Acid Ionization. A strong acid completely (or almost completely) dissociates in water, while a weak acid only partially dissociates. Step 3: : Ionization of HClO₄ (Perchloric Acid). For a strong acid like HClO₄, the ionization is essentially 100% complete. This means when dissolved in water, the reaction goes essentially to completion: Step 4: : Ionization of HClO₂ (Chlorous Acid). For a weak acid like HClO₂, the ionization is only partial. The reaction establishes an equilibrium: Step 5: : Quantitative Difference. - HClO₄: Virtually 100% of molecules dissociate into ions - HClO₂: Only a small fraction (typically 1-5%) of molecules dissociate into ions Step 6: : Practical Implications. - Strong acids like HClO₄ produce more H⁺ ions in solution - Weak acids like HClO₂ produce fewer H⁺ ions in solution Final Answer: The difference in ionization means that HClO₄ completely breaks apart into ions when dissolved in water, while HClO₂ only partially dissociates, leaving most molecules in their molecular form in solution.
