22. A 100.0-ml buffer solution is 0.175 M in HClO and 0.150 M in Nacio.
a. What is the initial pH of this solution?
b. What is the pH after addition of 150.0 mg of HBr?
c. What is the pH after addition of 85.0 mg of NaOH?
♦ Relevant knowledge
The principal function of buffer solutions is to ensure that the desired pH that is not subject to a significant change in spite of any additions of acid or bases to the mix that is already buffered. The precise mix of an acid that is weak with a suitable base for conjugation that is a weak acid results in an acidic buffer, whereas the precise mix of a weak base with an appropriate conjugate acid for the weak base is an essential buffer solution.
