2. You are handed a buffer solution that has equal concentrations of acid and conjugate base. Not knowing the species in solution, you predict the pH to be:

a) pH = 7.0, because the acid and base neutralize each other completely, having the same molarity
b) pH < 7.0, because buffers are always made up of an acid and its conjugate base, so the solution is always more acidic than basic
c) pH is unknown, because buffers can be formed at most pH's depending on the species forming the acid-base pair
d) pH is unknown, because a buffer solution is an equilibrium that can be pushed to either side
