Acids and Bases - Wyzant Lessons
solute concentration. This is the case for most weak acids. The only exceptions are when the strongest of the weak acids are in the most dilute solutions. If you have a stronger weak acid (one with a high k A), you should check to see if the [H +] is near 5% of the total solute concentration. If it is, you will have to use the alternative

Is HClO a Strong Acid? | Free Expert Q&A - bartleby
Weak acids, on the other hand, do not ionize completely. An aqueous solution with weak acids yields ions, but not all acid molecules break down. Even if a minuscule percentage of the acid remains intact, it is considered to be a weak acid. HClO, or hypochlorous acid, is such an acid. When added to water, it only dissociates partially. HClO ↔ ...
