Abstract
An adiabatic calorimeter was used to measure the enthalpy of solution of potassium tetrafluoroborate (0.01mol kg^-1 to 0.02 mol kg^-1) into water and into aqueous sodium fluoride of different ionic strengths (0.2 mol kf^-1 and 0.5 mol kg^-1) at 298 K and 313 K. The present results yield the standard-state enthalpy and heat capacity for the solution process, and, when combined with literature values for solubilities, yield the standard-state entropy of the solution process. From these properties, and previous measurements involving potassium tetrafluoroborate, we provide new analysis of thermodynamic properties of the aqueous tetrafluoroborate ion and compare these new properties to previous tabulations and explain the sources of discrepancies in the literature.
