Acid-base Equilibria and Calculations
This 48-page resource, intended for introductory level college chemistry courses, covers the quantitative treatment of acid-base equilibria. The principles of electroneutrality and mass balance are used to develop exact solutions for common equilibrium problems, and the common approximations and their limitations are explored. There is an extensive treatment of the use of log-concentration vs. pH graphs for obtaining approximate solutions of equilibrium problems without arithmetic. There is a detailed discussion of the proton-free energy concept, without the thermodynamics, that is helpful in understanding more complex acid-base systems. Other sections of this resource cover practical methods of solving quadratic and higher-order equations, graphical solution of equilibrium problems, titration curves, the carbonate system, physiological applications, and acid rain.
