a. The pH of the solution is equal to 7.00.
b. The volume of acid added from the buret equals the volume of base titrated.
c. The molarity of the acid equals the initial molarity of the weak base.
d. The percent ionization of the acid equals the percent ionization of the base.
e. The moles of acid added from the buret equals the initial moles of weak base.
