1. The problem statement, all variables and given/known data I'm stuck on these two problems: A) IF you make a 50 mL of a 0.1 M Tris solution (in acid form), what will be the pH? B) If you add 2 mL of 1 M NaOH to the above solution, what will be the pH? 2. Relevant equations pH = pka + log [A/HA] Hendersen-Hasselbalch 3. The attempt at a solution I'm not sure if HH is the right equation to use or not for this one when given both volume and concentration or if you add the NaOH to it. Help is greatly appreciated.
