5. Which statements are TRUE about the titration of a weak base B. with a strong acid?(1) At the equivalence point, the pH is calculated using the acid dissociation reaction of
the conjugate acid, BH+.
(2) Past the equivalence point, the excess strong acid determines the pH.
(3) Before strong acid is added, the solution contains just the conjugate acid, BH+.
(4) Between the initial point and the equivalence point, the solution contains a mixture of
B and BH+.
(5) The pH at the equivalence point is more than 7.0.
Your answer:
(A) (2), (4) and (5);
(B) (1), (2) and (3);
(C) (1),(3) and (4);
(D) (1), (4) and (5);
