4. Tris(hydroxymethyl)aminomethane [(HOCH2)3CNH2-Tris, or THAM] is a weak base
frequently used to prepare buffers in biochemistry. Its Kp is 1.2 x 10 6 and pKp is 5.92. The
corresponding pKa is 8.08, which is near the pH of the physiological buffers, and so it exhibits
good buffering capacity at physiological pH. What weight of THAM must be taken with 100 mL
of 0.50 M HCl to prepare 1 L of a pH 7.40 buffer?
5. Calculate the pH of a solution that is 0.200 M in NH3 and 0.300 M in NH4CI. Calculate the pH
change that takes place when a 100-mL portion of (A) 0.0500 M NaOH and (B) 0.0500 M HCl is
added to 400 mL of the buffer solution. Kb = 1.75 x 10-5
