Question

a) Calculate the initial pH of an unbuffered 0.100 M solution of hypochlorous acid, HClO, Ka = 3.5 x 10—8 b) Calculate the pH of the unbuffered solution in part a after addition of 0.020 moles of H+ to 1.0 L of the unbuffered solution. Recall that in an unbuffered solution, which has no base to bind to added H+, the added H+ remains as free H3O+ c) Calculate the initial pH of a buffered solution containing 0.10 M HClO and 0.10 M NaClO. d) Calculate the pH of the buffered solution in part c after addition of 0.020 moles of H+ to 1.0 L of the buffered solution. e) Calculate the changes in pH upon adding the H+ to the unbuffered and buffered solutions. Explain why there is such a huge difference between the change in pH of the unbuffered solution, as compared the change in the buffered solution. Specifically, tell what happens to the H+ which is added to the unbuffered solution HClO and explain how this different from what happens to the H+ in the buffered solution.

          a) Calculate the initial pH of an unbuffered 0.100 M solution of hypochlorous acid, HClO, Ka = 3.5 x 10—8
b) Calculate the pH of the unbuffered solution in part a after addition of 0.020 moles of H+ to 1.0 L of the unbuffered solution. Recall that in an unbuffered solution, which has no base to bind to added H+, the added H+ remains as free H3O+
c) Calculate the initial pH of a buffered solution containing 0.10 M HClO and 0.10 M NaClO.
d) Calculate the pH of the buffered solution in part c after addition of 0.020 moles of H+ to 1.0 L of the buffered solution.
e) Calculate the changes in pH upon adding the H+ to the unbuffered and buffered solutions. Explain why there is such a huge difference between the change in pH of the unbuffered solution, as compared the change in the buffered solution. Specifically, tell what happens to the H+ which is added to the unbuffered solution HClO and explain how
this different from what happens to the H+ in the buffered solution.
