Carbon Dioxide Equilibria and Their Applications

Carbon dioxide bicarbonate ion and carbonate ion comprise the most important acid-base system in natural waters and the equilibria between them regulate the pH of seawater as well as most rainwater stream water river water and groundwater. Carbon Dioxide Equilibria and Their Applications provides a clear compact presentation of this topic which is central to geochemistry and environmental engineering. It emphasizes a rigorous mathematical and thermodynamic basis for calculations and their application to realistic problems.The book's first four chapters present the basic equations mathematical techniques for visualizing and manipulating them and data on equilibrium constants and activity coefficients. These are presented in the general context of acid-base titration and solubility of CaCO3. The remaining chapters show how these concepts and techniques are applied to geochemistry and oceanography in addition to their applications to water conditioning. Specific topics discussed include acid rain freshwater seawater carbonate sediments in the deep oceans the effects of increased atmospheric CO2 on the oceans estuarine waters brines hydrothermal solutions pH adjustment prediction of calcium carbonate saturation corrosion inhibition and water softening.
