H solvation

H(solvated)]2+[Ce(N03)6]2 or more probably as [Ce(ether)2(N03)4]. Interference by phosphate ions can be eliminated by making the aqueous solution acidic with H2S04 and extracting liberated H3P04 into ether,...

Although the hydrogen ion is commonly written as H+, solvation is always assumed, as is the case for other ions such as Na+ or Fe2+.

H2 dissociation, H solvation, conversion of electrode potentials to the Fc scale, and entropy contributions that convert the free-energy based quantities (BDEq) obtained from E° and pK data to enthalpy-based BDEs. These terms have been extensively discussed and evaluated." Equation (7), Scheme 3 is the simple equation that is used... 

Following a similar approach, a Born-Haber cycle can be used to approximate the ability of other transition metal surfaces to activate water in the aqueous phase from the energetics of water activation in the vapor phase. This is quite useful since the vapor phase calculations are much less computationally intensive. The Born-Haber cycle for such a reaction scheme is given in Figure 19.3. The heterolytic activation of water over a metal surface is directly tied to the homolytic dissociation of water (Eq. 19.1) on that surface and the ease with which it can form protons from adsorbed hydrogen (Eq. 19.3). The specific steps in the Born cycle presented in Figure 19.3 include (1) the dissociation of H2O in the vapor phase to form OH(avapor phase)], (2) the desorption of H(ad) into the gas phase as H- [AE = Eb(n gas phase)], 0) the ionization of H to form H+ + e [A = E(h. ionization)], (4) the solvation of H [AE = E (h+solvation)], and (5) the capture of the electron by the metal surface [AE = — ]. The overall reaction energy for heterolytic aqueous-phase water activation, A , . , (aqueous phase), is ... 

As for proton formation from adsorbed hydrogen, E(. ionization), (h+ solvation) and Eb(u gas phase) are essentially metal independent (vide supra).
