B Ionic strength corrections
Table B-6: Ion interaction coefficients, ε 1 (j,k) and ε 2 (j,k), both in kg·mol –1 , for cations j
with k = Cl − , ClO4
− and NO3
− (first part), and for anions j with k = Li + , Na + and K + (second
part), according to the relationship ε = ε 1 + ε 2 log 10 I m at 298.15 K. The data are taken
from Ciavatta [1980CIA], [1988CIA] unless indicated otherwise. The uncertainties
represent the 95% confidence level.
