The Enthalpies of Solution and Neutralization of HF(l); Enthalpies of Dilution and Derived Thermodynamic Properties of HF(aq)
note HFbJohnson 1973 report {HF } + (1+0.63) {NaOH } -> {NaF } + 0.63 {NaOH } an enthalpy of -21017 +- 9 cal/mol. They further assume that {NaF } -> {NaF } + 0.63 {NaOH } has an enthalpy of 0 +- 5 cal/mol. They also use the dilution enthalpies for {NaOH } -> {NaOH } of -101 +- 5 cal/mol and {NaF } -> {NaF } of -101 +- 5 cal/mol from Parker 1965. These conviniently cancel such that {HF } + {NaOH } -> {NaF } + {H2O } -21017 +- 29 cal/mol.
