Ⅰ.在上题的文中(以下简称文献),作者遗漏了Bates等一文,因此根据下面的假设,计算邻硝基苯甲酸(HA)在高氯酸纳水溶液中的活度系数: γHA(N2CIO4)=γ0.01HBr(NaClO4(1) γHA(NaClO4)=γ0.01HBr(NaClO4)+γNaClO4—γNaBr(2) 算出结果列于文献表2第6行(γ±即γHA(盐)的缩写),并根据这些γ±值,计算)y±,CH+,…,等值.

In the arricle of the above title [1],we missed the paper of Bates and Urmston [2] which contains the data of the activity coefficients of HCl in aqueous NaCl4 solution,γHCl[NaClO4 and calculated γ0.01HCl[NaClO4](which was taken as γHA[NaClO4],HA=o-nitro-benzoic acid) by making certain assumptions.We now take their values of γ0.01HCl[NaClO4 as γHA[NaClO4]] and recalculate the salting-out constant,k.
