Autoprotolysis mechanism

Therefore, an autoprotolysis mechanism was proposed consisting of dissociation ... 

The following expression for the inverse proton life times follows from the autoprotolysis mechanism in CH3OH a straightforward way [93]... 

Although the reaction has the overall stoichiometry of a dehydration it is more complex than this and involves a mutual redox reaction between N and N. This is at once explicable in terms of the volt-equivalent diagram in Fig. 11.9 which also interprets why NO and N2 are formed simultaneously as byproducts. It is probable that the mechanism involves dissociation of NH4NO3 into NH3 and HNO3, followed by autoprotolysis of HNO3 to give N02, which is the key intermediate ... 

Despite this enormous viscosity, fused H3PO4 (and D3PO4) conduct electricity extremely well and this has been shown to arise from extensive self-ionization (autoprotolysis) coupled with a proton-switch conduction mechanism for the... 

H2SO4.Z2H2O, are known with = 1, 2, 3, 4 (mps 8.5", -39.5". -36.4" and -28.3% respectively). Other compounds in the H2O/SO3 system are H2S2O7 (mp 36") and H2S4O13 (mp 4"). Anhydrous H2SO4 is a remarkable compound with an unusually high dielectric constant, and a very high electrical conductivity which results from the ionic self-dissociation (autoprotolysis) of the compound coupled with a proton-switch mechanism for the rapid... 

These processes are interfacial protolytic equihbria existing between the large number of active sites on the surface and H+/OH ions in the aqueous medium, which are the product of a water autoprotolysis reaction (H2O H -I- OH ). The question of our approach or the choice of model by which the surface-charging mechanism can be described is whether to consider them a surface association-dissociation or an interfacial adsorption-desorption equilibria. Charging of an amphoteric oxide surface can be modeled with a simple one-step protonation reaction [14] ...
