The following drawings represent solutions at various stages of the titration of a weak acid, HA, with NaOH. (The Na+ ions and water molecules have been omitted for clarity.) To which of the following regions of the titration curve does each drawing correspond:

(a) Before addition of NaOH,

(b) After addition of NaOH but before equivalence point,

(c) At equivalence point,

(d) After equivalence point? [Section 17.3]
