Be sure to answer all parts. Tris [tris(hydroxymethyl)aminomethane] is a common buffer for studying biological systems. (K, = 5.01 x 109 and pK, = 8.3) %3D (a) Calculate the pH of the Tris buffer after mixing 11.0 mL of 0.20 M HCI solution with 25.0 mL of 0.10 M Tris. (b) This buffer was used to study an enzyme-catalyzed reaction. As a result of the reaction, 0.00019 mol of H* was produced. What is the pH of the buffer at the end of the reaction? (c) What would be the final pH if no buffer were present? Be sure to answer all parts. Tris [tris(hydroxymethyl)aminomethane] is a common buffer for studying biological systems.
