🤓 Based on our data, we think this question is relevant for Professor Schreiber's class at WMU.
The following pictures represent solutions at various points in the titration of a weak acid HA with aqueous KOH. Unshaded spheres represent H atoms, black spheres represent oxygen atoms, and shaded spheres represent A- ions. (K+, H3O+, initially present, OH - initially present, and solvent H2O molecules have been omitted for clarity).
Which picture below represents the solution at the equivalence point?
(e) None of the above.
