Questions 2 and 3 pertain to the following scenario: A pharmacist wishes to prepare 2 L of stock buffer solution using ammonium chloride and ammonia to yield a pH of 8.66 for topical use. pka = 9.26 MWNH3 17.03 g/mol 2. What is the molar ratio of ammonium chloride and ammonia required? MWNHACL = 53.49 g/mol 3. If the molar concentration of the buffer is 25 mmol/L, how many milligrams of ammonium chloride and ammonia are required to produce the buffer solution in Question 2?
