1. Calculate the pH for the following solutions. (Since these are all buffers, you may use the Henderson-Hasselbalch equation!) a. 10.0 mL 50 mM Tris + 40.0 mL 50 mM Tris-HCD b. 25.0 mL 50 mM Tris + 25.0 mL 50 mM Tris-HCD c. 25.0 mL 50 mM KH₂PO4 + 25.0 mL 50 mM Na2HPO4 TrisH* K₂ = 8.51 x 10-9 H3PO4 2. What is the acid and base buffer capacity for each buffer in problem #1. Ka1 = 7.5 x 10³, Ka2 = 6.2 x 108 Ka3 = 4.8 x 10-13 1. Calculate the pH for the following solutions.
