1) One of the most common buffers used in biological applications is Tris H*/Tris: OH OH Hogar НО. OH OH NH3 Tris H* (K, = 7.94 x 10-) HO NH2 Tris la) What is the pH of 0.75 L of Tris buffer containing 13 mmol Tris H* and 11 mmol Tris? + 1b) You add 0.020 L of 0.15 M HCl to the exact buffer solution from part (a). What is final pH? Partially filled ICE table provided for convenience, units in mmol Tris H Tris 13 11 с E 1c) To a fresh 0.75 L portion of Tris buffer identical to that in part (a) you add 0.10 L of 0.15 M HCI. What is final pH? Partially filled ICE table provided for convenience, units in mmol Tris н" Tris H 13 11 C E
