Which acid will dissociate more in a mixture of 0.10 mol of HF and 0.10 mol of HOCl?
Understand the Problem
The question is asking which acid will dissociate more in a mixture of hydrofluoric acid (HF) and hypochlorous acid (HOCl). It suggests that the dissociation is influenced by their respective acid dissociation constants (Ka) and relative pH levels.
Answer
HF dissociates more than HOCl in the mixture.
The dissociation of HF (hydrofluoric acid) is greater than HOCl (hypochlorous acid) in this mixture because HF has a higher acid dissociation constant (Ka).
Answer for screen readers
The dissociation of HF (hydrofluoric acid) is greater than HOCl (hypochlorous acid) in this mixture because HF has a higher acid dissociation constant (Ka).
More Information
HF is a stronger acid compared to HOCl as indicated by their dissociation constants. This means HF releases more hydrogen ions in solution under the same conditions, resulting in greater dissociation.
Tips
A common mistake is assuming both acids dissociate to the same extent due to identical concentrations without considering their dissociation constants.
