An interionic bond forms when a highly electropositive metal ion is combined with a highly electronegative non-metal ion.
Silicon is more electropositive than carbon and this gives rise to the siloxane bond having a fairly significant degree of ionic character; it is empirically calculated to be 40-50%.

Thus, there is a microbiologically mediated sequence of redox processes in sediment, from the most electropositive to the most electronegative: [O.sub.2]/ [H.sub.2]O > N[O.sub.3.sup.-]/[N.sub.2] > Mn[O.sub.2](s)/[Mn.sup.+2] > FeOOH(s)/[Fe.sup.+2] > S[O.sub.4.sup.-2]/ HS- > C[O.sub.2]/C[H.sub.4] (Stumm and Morgan, 1996).
The alkaline solution (alkaline EO water) is produced at the cathode when the saline water dissociates into hydroxyl ions due to the strong electropositive nature of the Na+ ions, which later bind with sodium to form sodium hydroxide (NaOH) and hydrogen (H2) gas, and hence is called the catholyte.

The standard redox potential (Thauer et al., 1977) for N[O.sub.3.sup.-] reduction to N[H.sub.4.sup.+] is more electropositive ([E.sub.0]' = 0.37V) than that for HC[O.sub.3.sup.-] reduction to C[H.sub.4] ([E.sub.0]' = -0.24 V).
In early works (33), (34), most of the authors considered this type of compounds as "ate" complexes in which the complex anion is associated with the most electropositive metal (36).
