please show me how to do it on excel (including the graph) thank you!!

6. The alpha values for any weak acid with n ionizable protons, H.A. can be written as follows: [HnA] [H3O+]" D . CT 1 [Hn-14) Kai(H30*j*-1 [Hn-2A-2) Kat Kaz[H3O+]n-2 D D : [A-") Kai Kaz...Kan[H3O+jn-n D where Cr is the analytical concentration of the acid and the denominator Dis given by D = [H30*]" + Ka: [H30*](3-1) + Ka, Kaz[H30*(-2)+ --Kaz Kaz -- Kan Calculate the alpha values for the triprotic acid, phosphoric acid, for every 0.5 pH units from pH-0.0 to pH - 14.0. (pKat 2.12, pK2=7.21.pKs = 12.67), Plot the distribution diagram. Label cach species and use a different color for cach of the species' data points and lines
