Which statement correctly distinguishes between the equivalence point and the end point in an acid–base titration?
(a) At the equivalence point the pH is always 7, whereas the end point can occur at any pH.
(b) The equivalence point is identified by the first permanent color change of the indicator, while the end point is reached when equal volumes of acid and base have been mixed.
(c) The equivalence point is when stoichiometric amounts of reactants have reacted, whereas the end point is the observable indicator change that should coincide with it.
(d) The end point and equivalence point are the same as long as a strong acid is titrated with a strong base.
