Which statement best defines the equivalence point in an acid–base titration?
(a) The point at which the solution’s pH is exactly 7.0, regardless of the acids or bases involved.
(b) The midpoint of the steepest section of the titration curve where pH=pKa.
(c) The point at which the number of moles of titrant added equals the number of moles of analyte originally present.
(d) The volume at which the indicator first shows a permanent color change.
