WebHydrochloric HCl Cl-Chloric HClO3 ClO3-Sulfuric (1) H2SO4 HSO4-Nitric HNO3 NO3-Strong acids completely dissociate in aq solution (Ka > 1, pKa < 1). Conjugate bases of strong acids are ineffective bases. Hydronium ion H3O+ H2O 1 0.0 Iodic HIO3 IO3-1.6 x 10-1 0.80 Oxalic (1) -2H2C2O4 HC2O4 Web(ii) Explain why the pH of buffer 1 is different from the pH of buffer 2 after 0.10 mol of HCl is added. Before the HCl was added, each buffer had the same pH and thus had the same [H +]. Because K a for acetic acid is a constant, the ratio of [H ] to K a must also be constant; this means that the ratio of [HC 2 H 3 O 2] to [C 2 H 3 O 2 −]
