Why is my professor using an ice table to solvs this
titration problem? I seem to be confused with titrations and when
to use an ice table with these kinds of problems. Iv seen similar
problems being done without an ice table. Please break it down step
by step explaing when and why we use ice tables to solve a
titration question.

Not sure about my answers. So I would like to see Half
equivilance point, pKa, Ka and molarity of acid values worked out
from these graphs. Impotant data: titration of 25.00 +/- 0.01 mL of
unknown acid by 0.1069 M NaOh. Two runs were done, but data
calculations for ony one is needed now (they sets are nearly
identical)..

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...
