1) The Pka value for HClO is 7.46. Would a buffer prepared from HClO and KClO with a pH of 6.96 be considered to be an effective buffer?

2) A buffer in which the mole ratio of KClO to HClO is 2.3 has a pH of 7.82. Would this buffer solution have a greater capacity for added acid (H3O+) or added base (OH-)?

3) A buffer solution that is 0.385 M in HClO and 0.385 M in KClO has a pH of 7.46. Addition of which of the following would increase the capacity of the buffer for added H3O+? Select all that apply:

a) pure water

b) HClO

c) Both HClO and KClO simultaneously

d) KClO

e) None of the above
