Terminology of Acid-Base Titrations

Acid-base titrations are also ealled prototropic titrations or acidimetric and alkali-metric titrations. Aceording to the lUPAC, the term aeidimetric titration is reserved for the titration of a base with a standard aeid solution. It is the opposite of the term alkalimetric titration. In France, the two terms eonnotations completely oppose those recommended by the lUPAC. 

2 General Considerations Concerning Add-Base Titration Curves Fraction Titrated 

Let s consider the volume Vo (em ) of the solution of an acid (or a base) of concentration Co mol/L that we want to titrate with a solution of a base (or of an aeid) of concentration C. At each titration stage, the added volume is F(cm ) (Fig. 9.1). 

The acid-base titration curve or neutralization curve is the diagram given by the pH of the solution as a funetion of the volume V (Fig. 9.2). 

Equivalently, neutralization curves are also the diagrams of pH/tp, where cp is the fraction titrated. It is the ratio of the number of moles of added titrant and the initial number of moles of the titrand
