In the titration of a weak acid with a strong base, the pH at the equivalence point is affected mostly by
a.hydrolysis (reaction with water) of the weak acid
b.the dissociation of water molecules
c.the presence of excess base
d.the hydrolysis of the conjugate base of the weak acid
e.the presence of a small amount of weak acid in equilibrium with its salt
Really confused by this question.. please help T^T thanks.
