【Abstract】 In the article of the above title, we missed the paper of Bates and Urmston which contains the data of the activity coefficients of HCl in aqueous NaClO₄ 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.At the time of publication of the article mentioned, lack of data of γHA[Me₄NBr] and γMe₄NBr in the literature forced us to assume γHA[MeNBr]=γ0.01HBr[KBr] for the calculation of k. The appearance of Lindenbaum and Boyd’s paper, this spring, which contains the data of the activity coefficients of tetraalkylammonium halides, enables us to calculate γ0.01HBr[MeBr] （which is taken as γHA[Me₄NBr]） by using similar assumptions.The two new values of k’s, when placed among those of the other salts studied in[1], require no change in the salting-out order given.更多还原
