Figure 3. 17 shows the way in which the "concentration profiles" develop with
time and it can be seen qualitatively that the flux at x = L increases with time.
Figure 3.18 considers further the experiment where the concentration of i in
solution A is ...

Some important distinctions between electrodialysis and other electromembrane
processes are presented in figure 4.1. Figure 4.1(a) illustrates the electrolysis of
aqueous sodium chloride in an undivided cell. When NaCl is dissolved in water,
