Prediction of the density of ammonium bisulfate solutions


The concentration dependence of the density of ammonium bisulfate solutions has recently been studied. It was found that the NH₄HSO₄ solution densities calculated from the data for the molarities of NH₄HSO₄, [NH₄HSO₄], and water, [H₂O], in Table I of Irish and Chen differed substantially from available data. The objective of this communication is twofold: (a) to determine the source of this discrepancy, and (b) to ascertain whether the extent of bisulfate dissociation in NH₄HSO₄ solutions is accurately represented by the data in Irish and Chen. The validity of the NH₄HSO₄ molarity and extent of bisulfate dissociation data in that table will be determined by comparing predicted and measured NH₄HSO₄ solution densities.
