Inner-spher

Since cations are adsorbed electrostatically not only due to the permanent structural charge, oq (caused by isomorphic substitution), but also due to the proton charge, (the charge established because of binding or dissociating protons), the ion exchange capacity is pH dependent (it increases with pH). Furthermore, the experimentally determined capacity may include inner-spher-ically bound cations. 

There is no structure for an elongated core intermediate between that shown in Fig. 11, with three inner-core spher-ons, and that shown in Fig. 12, with four. The transition between these structures is calculated by use of Eq. 1, with n, = 22, to occur at nt = 69, that is, at N = 138. It is accordingly an expectation from the close-packed-spheron theory that, as observed, 90Ac13a2- 7 (formed by bombardment of Re- 20 with 11-Mev protons) gives a three-humped fission product distribution curve (23), which has been interpreted (24) as showing that both symmetric fission and asymmetric fission occur. 

In aqueous solution, electron transfer between two solute redox reactants A+ and B may occur either by an outer-spher (o.s.) or an inner-sphere (i.s.) redox mechanism (ET stands for electron transfer)...
