Debye and Hueckel assumed that ions interact electrostatically like charged par-tides of zero size, but ions and their associated water molecules have significant physical size. These and other problems make Eq. 3.16 unreliable at ionic strengths greater than about 0.01. The equation has been modified to be useful up lo 7 =0.1 ...
