A)At the equivalence point,the solution has excess moles of strong base.
B)At the equivalence point,the solution is acidic.
C)At the equivalence point,the solution has excess moles of weak acid.
D)At the equivalence point,the solution is composed of the conjugate base of the weak acid.
E)At the equivalence point,the pH is 7.

At the equivalence point of the titration of a weak monoprotic acid with a strong base, the solution is composed of the conjugate base of the weak acid. This is because the strong base has completely reacted with the weak acid, converting it to its conjugate base. The pH at the equivalence point is not necessarily 7, as the resulting solution may be acidic or basic depending on the strength of the weak acid and base. Options A, B, and C are incorrect because they suggest an excess of one reactant at the equivalence point, whereas the point is defined as the point at which the moles of acid and moles of base are equal.
