These standard molar values apply to (infinitely) dilute aqueous solutes at 25oC and exactly 100 kPa (1.0 bar) pressure. One standard atmosphere pressure is slightly higher, 101.325 kPa, but the change in tabulated values between these two pressures is neglegible for all solids, liquids, and ions. It is minor even for gases. Values are taken from U.S.N.B.S. tables of molar thermodynamic properties (J. Phys. Chem. Ref. Data 11, Suppl. 2 (1982)) unless in italics.
