If Kb=5.6x10^-10, calculate the pH of a solution that is 0.25 M NaCH3C00. (Ans 9.08)
The pH of a solution is 6.30. What are [H30+1] and [OH-1) in the solution? Kw = 1.0 x 10-14 at 25°C 1) [H3O+] = 5.0 x 10-7, (OH"] = 2.0 x 10-8 O2) [H30*) = 6.3 x 10-7. [OH-] = 7.7 x 10-8 3) (H30+1 = 2.0 x 106, (OH") = 5.0 x 107 O4) [H30+) - 2.0 x 10-8, (OH") = 5.0 x 10-7 5) [H3O+] = 1.6 x 10-1 (OH'] = 1.3 x 10-1
