I asked this before, but got no response.

A) If you make up a solution of 250 mL of 0.1 M TRIS in the acid form, what will be the pH?

B) If you add 2 mL of 1 M NaOH to the solution in part A, what will be the pH?

Thanks.

  1. for A, correction: it is actually 50 mL of a 0.1 M TRIS.

    Here is the answer I got for A:
    A) pH= 2.3

    For B, I got

    pH= 1.2
