Gas-phase + conventional properties

Recommended data for the standard thermodynamic parameters of alkali, halides and hydrogen (book Table 5.22). The reported data includes the atomization enthalpy Δ_aH^ɵ, the molar entropy s^ɵ, the molar heat capacity c_P^ɵ, the molar volume v^ɵ, the molar volume-compressibility k_T^ɵ and the molar volume-expansivity a_P^ɵ of the alkali and halide or hydrogen elements (I_el), the ionization enthalpy Δ_iH^ɵ, the molar entropy s^ɵ, the molar heat capacity c_P^ɵ, the molar volume v^ɵ, the molar volume-compressibility k_T^ɵ and the molar volume-expansivity a_P^ɵ of the alkali and halide or hydrogen gas-phase atoms (I_g), the molar entropy s^ɵ, the molar heat capacity c_P^ɵ, the molar volume v^ɵ, the molar volume-compressibility k_T^ɵ and the molar volume-expansivity a_P^ɵ of the alkali and halide gas-phase ions or of the gas-phase proton (I_g^z), the conventional hydration free energy Δ_sG^•, the conventional hydration enthalpy Δ_sH^• and conventional hydration entropy Δ_sS^• of the alkali and halide gas-phase ions or of the proton (I_g^z), the conventional partial molar entropy s^•, the conventional partial molar heat capacity c_P^•, the conventional partial molar volume v^•, the conventional partial molar volume-compressibility k_T^• and the conventional partial molar volume-expansivity a_P^• of the aqueous alkali and halide ions or of the aqueous proton (I_aq^z), as well as the standard work function ω^ɵ of the alkali metals (M_s) and of platinum Pt_s (values between parentheses). The entries ε provide error estimates on the conventional solvation parameters and partial molar variables in aqueous solution reported in the preceding lines. The standard states are according to the bbme_T convention (reference pressure P^ο=1 bar, reference molality b^ο=1 mol·kg^-1 and reference temperature T^-=298.15 K; standard state for the free electron according to the warm-electron convention: ideal-gas at temperature T^-, according to Fermi-Dirac statistics; Fermi-Dirac statistics is also applied for the gas-phase standard state of the proton; the work functions refer to polycrystalline surfaces). The solvation parameters and partial molar variables in solution are assumed here to pertain to the standard (Δ_sG^•, Δ_sH^•, Δ_sS^•, s^•, c_P^•) or the density-corrected (v^•*, k_T^•*, a_P^•*) variant, which represents the most likely situation, but may not necessarily be the case in reality. The conventional solvation free energy (Δ_sG^•) is identical in the two variants.
