I just made the neg to a pos and finished the problem. I got pH=6.3 for a final answer. hope that is what you came up with.

chemistry
Here are instructions on how to solve it. Would you help me step by step with the math and instructions?: Heres how to solve it: Use the Henderson-Hasselbalch equation. pH = pKa + log ([Tris] / [Tris HCl]). Here the pH is 8 and the pKa of the Tris is 8.3, so you can solve for ...

Interesting choice, I would have totally choose a republic, LOL, but If you wnat you could write it in the view of yourself. Put personal things into it, but not, date it as a journal entry, maybe just relax and let you brain think of what you want ot write.
