Asolution contains 0.45 m hydrofluoric acid (hf; ka = 6.8 x 10−4). write the dissociation reaction. determine the degree of ionization and the ph of the solution

Degree of ionization = 0.0377

pH of the solution = 1.769

Explanation:

Initial concentration of HF = 0.45 M

Initial        0.45                             0          0

At equi      0.45 - x                      x           x

Equilibrium constant =

x = 0.017 M

x = Cα

α = Degree of ionization

C = Concentration

Degree of ionization =

[H^+]=0.017 M

             = 1.769
