Question:

You wish to prepare a buffer solution with pH = 9.45.

(a) How many grams of (NH4)2SO4 would you add to 425 mL of 0.258 M NH3 to do this? Assume that the solution’s volume remains constant.

(b) Which buffer component, and how much (in grams), would you add to 0.100 L of the buffer in part (a) to change its pH to 9.30? Assume that the solution’s volume remains constant.
