6. The alpha values for any weak acid with n ionizable protons, HaA, can be written as
follows:
[HnA] [H30+j"
Ст
D
[Hn-1A-11 Ka1(H30*]"-1
Ст
[Hn-24-2] KaiKaz[H30+]n=2
Ст
D
[A"] KaiKaz...Kan[H30*]"-n
Ст
D
where CT is the analytical concentration of the acid and the denominator D is given by:
D = [H30*]" + Kai[H30*]n=1) + Kai Kaz[H30*](n-2)+... KaıKaz ** Kan
Calculate the alpha values for the diprotic acid, oxalic acid, for every 0.5 pH units from pH
= 0.0 to pH = 14.0. (Kal =5.4 x 102, Ka2 5.4 x 10). Plot the distribution diagram. Label
cach species and use a different color for each of the species' data points and lines.
