Be sure to answer all parts. The following diagrams represent solutions at various stages in the titration of a weak acid, HA, with NaOH. Identify the solution that corresponds to the states described below. (Water and Na ions have been omitted for clarity.) h5bur17341 (1) The initial stage before the addition of NaOH: (a) (b) (c) (d) (2) Halfway to the equivalence point: (a) (b) (c) (d) (3) The equivalence point: (a) (b) (c) (d) (4) Beyond the equivalence point: (a) (b) (c) (d) Is the pH greater than, less than or equal to 7 at the equivalence point
