Problem

The following diagrams represent aqueous solutions of three acids, HX, HY, and HZ. The water molecules have been omitted for clarity, and the hydrated proton is represented as a simple sphere rather than as a hydronium ion.
With HX, there are five HX molecules and two positive and two negative ions present.  With HY, there are zero HY molecules and eight positive and eight negative ions present.  With HZ, there are four HZ molecules and three positive and three negative ions present.
Which acid would have the smallest acid-dissociation constant, Ka?
