a Data are mostly f rom The NBS Tables of Chemical Thermodynamic Properties, D. O. Wagman
et al., J. Phys. Chem. Ref. Data 11, Supplement No. 2 ^1982h. The values for ions in aqueous
solution ^1Mh, such as Li+^aqh, are based on the convention that all the properties listed for
H+^aqh are equal to zero.
