1. A buffer called "Tris" is widely used in biochemistry. The (neutral) compound "Tris" itself is a weak base, so we'll notate it as "B." The pk, of its conjugate acid (HB) is 8.07. The overall goal of this problem is to calculate the pH change of a Tris buffer upon addition of some strong base. (a) Assume that you have a pH 8.40 Tris buffer...
