Introduction

Abstract

Acid–base diagrams, better called pH-logc _i diagrams, are the most beneficial tools which have been developed to describe acid–base equilibria. They present the interrelations between the logarithm of all equilibrium concentrations c of the species i and the pH value of the solution. They make it possible, without any math calculations, to find the approximate pH of solutions of acids and bases and buffers. They can be also applied to find out what approximations in the math calculations of the pH (or concentration of any species) are allowed under certain conditions. These acid–base diagrams can also be used to construct titration curves in order to extract the most important data, such as pH at the equilibrium point, etc. A good training in using these diagrams is necessary for a wide range of science studies. The present book provides the basics as well as a good number of applications.
