Explanation / Answer

part A)

HC3H3O2    ------------> C3H3O2-   +   H+

0.150                                  0                 0

0.150 - x                              x                  x

Ka = x^2 / 0.150 - x

5.623 x 10^-5 = x^2 / 0.150 - x

x = 2.90 x 10^-3

pH = -log [H+] = -log (2.904 x 10^-3)

pH = 2.54

part B)

[H3O+] = 2.9 x 10^-3 M

part C)

[C3H3O2-] = 2.9 x 10^-3 M

part D)

[HC3H3O2] = 0.147 M

part E)

[OH-] = 3.4 x 10^-12 M

part F)

% dissociation = 3.5 %
