Alkalinity analytical definition

If bases other than the carbonates and OH are present that react with protons in the pH range of the alkalinity and acidity titrations, we cannot use these calculations and diagrams without modifications. In addition the analytical definition of acidity and alkalinity must be changed to incorporate these bases. The following reactions are important in this regard in waters and wastewaters. 

The conclusions to be drawn from the analytical results are as with diffusion juices. The alkalinity and the lime content are of importance since definite limits have been established for them in different cases. Defecated juices should be alkaline, but if the alkalinity is too high, loss of sugar may occur during the subsequent concentration of the juice. 

There are two kinds of acidity or alkalinity components in natural systems (1) acidity or alkalinity dissolved in water, and (2) acidity or alkalinity present in the solid phase. The solid-phase acidity or alkalinity represents the reservoir of acidity or alkalinity encountered in water. By definition (commonly employed by commercial analytical...

We can define alkalinity and acidity in two ways operationally and analytically (or mathematically). Let us first examine the operational definition of alkalinity and then proceed to see how this is related to the mathematical definition when the components of the solution contributing to the alkalinity are only carbonate species and OH". 

The Operational Definition of pH The utility of pH as a measure of the acidity or alkalinity of aqueous media, the wide availability of commercial glass electrodes, and the proliferation of inexpensive solid-state pFf meters have made the potentiometric measurement of pH one of the most common analytical techniques in all of science. It is thus extremely important that pH be defined in a manner that is easily duplicated at various times and vari-...
