The molar ratio used by Li [2] in his experiments is in the rangeM=
11–17, H = 12–18. The corresponding concentration of MgCl2 is from
3.084 mol · kg−1 to 4.626 mol · kg−1. The ionic strength of these
MgCl2 solution is 15 mol · kg−1 which is beyond the capability of commonly
used aqueous models, such as Debye–Hückel Theory
