Notes: These molar values apply to pure substances at 25oC and exactly
100000 Pa (1.0 bar or 100 kPa) pressure. One standard atmosphere pressure is
slightly higher, 101325 Pa, but the change in tabulated values between these
two pressures is neglegible for all solids and liquids and minor even for
gases. Physical states are indicated by c (crystalline solid), l (liquid),
and g (gas). Different crystalline structures are designated by common or
mineralogical names. Common names for selected compounds are also given.
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.

Notes: 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.

Notes: Values for 0.1 MPa and 25oC in aqueous 1.0 molar acid solution,
calculated from U.S.N.B.S. tables of molar thermodynamic properties unless
in italics. The potential values are given to the nearest 0.1 mV if known,
thermal coefficients to the nearest 0.001 mV/K if known. The thermal
coefficient is that of the isothermal cell in which one of the electrodes is
the standard hydrogen electrode. Ions are all aqueous. Elements and
compounds are pure substances, present in their usual state at 25oC, unless
otherwise indicated. The saturated calomel reference potential is the
experimental value for pure mercury in contact with an aqueous solution
saturated with both Hg2Cl2 and KCl.
