1. Calculate either [H3O+] or [OH] for each of the solutions at 25 C.

Solution A: [OH]=1.57107 M; [H3O+]=

Solution B: [H3O+]=9.97109 M; [OH]=

Solution C: [H3O+]=6.75104 M; [OH]=

Which of these solutions are basic at 25 C? ( PICK all that applies)

Solution A: [OH]=1.57107 M

Solution B: [H3O+]=9.97109 M

Solution C: [H3O+]=6.75104 M

2. f the a of a monoprotic weak acid is 3.4106, what is the [H+] of a 0.29 M solution of this acid?
