DETERMINATION OF ACTIVITY COEFFICIENTS OF PERCHLORIC ACID IN SYSTEM OF HCl-HClO4-H2O
Abstract:
Mean activity coefficients of perchloric acid in system of HCl-HClO_4-H_2O at a constant total ionic strengths (I=0.7, 0.5, 0.3 and 0.1) have been measured by E.M.F. method from a cell without liquid junctions. The cell consists of a perchloric ion sensitive electode and a glass electrode. Results obtained show that the relationships between the logarithm of the mean activity coefficients of perchloric acid and the concentration of each of the two acids in the above mixtures obey Harned's rule. The respective Harned's coefficients a_(21) have been computed by the least square method.
