Chapter 17, Problem 15E

You wish to prepare a buffer solution w pH = 945
a. How many grams of ${\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{SO}}_{\text{4}}$ , would you add to 425 mL of 0.258 M NH₂ to do thee Assume that the solution’s volume remains constant
b. Which buffer component, and how much (in grains), would you add too 0.100 L of ma buffet in part (a) to change its pH to 930? Assume that the solution s volume remains constant.
