WebMar 14, 2024 · Thus, a solution of this salt will have a pH <7 (acidic). We will find the pH by looking at the hydrolysis of the conjugate acid. C5H5NH + + H2O ==> C5H5N + H + Now we need the Ka for C5H5NH + which I looked up and found to be 5.6x10-6 Ka = [C5H5N] [H +] / [C5H5NH +] 5.6x10-6 = (x) (x) / 0.10 x 2 = 5.6x10 -7 x = 7.48x10 -4 M = [H +] pH = -log [H +] WebL of 0.1 M KCN (pH 7, adjusted with acetic acid). The dialysis was repeated until no blue color was observed. The cyanide was removed by dialysis against ammonium acetate (0.05 M, pH 8). UV absorption data of Apo-Az showed no absorption peak at 625 nm, indicating the complete removal of the copper ion.S2
