1) Consider the titration of a weak acid with a strong base at the equivalence point. Choose all true statements that apply.

 

a) The pH is equal to the pKa of the acid.

b) All of the weak acid originally present in the solution has been converted into its conjugate base.

c) The moles of weak acid and its conjugate base are equal in the solution.

d) The moles of weak acid originally in the solution is equal to the moles of strong base added.

 

2) In a titration of a weak acid with a strong base, how is the pH calculated at the equivalence point?

a) Using weak base equilibrium

b) Using the concentration of a strong acid

c) Using weak acid equilibrium

d) Henderson-Hasselbalch equation

E) Using the concentration of strong base.
