Problem
In an acid–base titration, which statement best describes the equivalence point?
(a) It occurs when an equal volume of titrant has been added as the volume of analyte present at the start of the titration.
(b) It is the point at which the moles of titrant added equal the stoichiometric amount required to react completely with the analyte.
(c) It is the first observable color change of the indicator, regardless of stoichiometry.
(d) It is reached when the pH of the solution is exactly 7.00, independent of the reactants used.
