Simple Equilibrium Theory for Reactions Involving Aqueous Hydrogen Ions

Simple Equilibrium Theory for Reactions Involving Aqueous Hydrogen Ions 

An algebraically very simple theory can be developed from a set of five assumptions. As will be shown, its predictions are reasonably borne out by a fair body of data. It is now generally accepted as a suitable basis for discussing simple cases. It can be adapted to meet special circumstances and extended to overcome some of the weaknesses of the assumptions. Indeed, exception can be taken (and has been taken) to nearly every one of these assumptions, and the extent of their validity and the need for modification of the theory are further discussed in Section IV. 

The best available direct experimental measurements favour a value of 0-69 + 0-01 or 0-02 for l (Gold, 1963 Kresge and Allred, 1963 Heinzinger and Weston, 1964a). 

Fractionation factors for hydrogen-containing solutes other than the hydrogen ion are represented by the symbol f , the formal definition being 

The symbol FXLm is the fractional abundance of deuterium in the solute XLm and n that in water.
