Broensted acid-base reactions solution

What evidence is there for the individual reaction steps The acid-base reaction (Eq. 2) has the characteristics of a Broensted equilibrium, as has been shown in the case of diazomethane-benzoic acid (in toluene).4 Further evidence for this is provided by the reactions of diazoacetic ester and diazo ketones.6 7 The occurrence of free, mobile diazonium cations is also supported by the fact that solutions of diazomethane in methanol show greater conductivity than solutions of pure solvent.8... 

The donor-acceptor principle is an important basic concept in modern chemical education acid-base reactions, redox reactions and complex reactions explain a huge number of chemical changes. One important group of donor-acceptor reactions are the acid-base reactions protons (H+ ions) transfer from one species to another species. One example, in the neutralization of sulfuric acid with sodium hydroxide a proton is moving from one hydronium ion H30 + (aq) of the acid solution to one hydroxide ion OH (aq) ion of the hydroxide solution. Broensted s key concept will be considered in this chapter. 

In 1923, Broensted was the first to develop an acid-base concept that was no longer related to substances, but rather to the function of particles. Acids are proton donors and are capable, with suitable reaction partners, to donate protons to base particles or proton acceptors, i.e. protolysis or proton transfer reaction. For example, HC1 molecules, as acid particles, transfer protons when colliding with H20 molecules (see Fig. 7.3). In this sense, the proton donors of pure sulfuric acid are H2S04 molecules, the acid particles of the sulfuric acid solution are the hydronium ions (or also the hydrogen sulfate ions in concentrated solutions). In weak acids, the protolysis equilibrium is to be considered, equilibria and their constants are well defined.
