Dilution enthalpies of the binary systems (LiBO2 + H2O) and (LiB5O8 + H2O) and the ion interactions at 308.15 K

Microcalorimeter measured the dilution enthalpies of the binary systems (LiBO 2  + H 2 O) and (LiB 5 O 8  + H 2 O) at 308.15 K and 0.1 MPa. Based on the Pitzer theory of electrolytes, their apparent molar enthalpies and the Pitzer single electrolyte parameters at 308.15 K were carried out by fitting the experimental data for the first time. Moreover, the calculated apparent molar enthalpies of LiBO 2 and LiB 5 O 8 aqueous solution according to the Pitzer ion-interaction model were consistent well with the experimental values, manifesting the high reliability of this study.
