Course objectives
At the end of the course students should be able to understand and explain advanced knowledge in the field of aqueous geochemistry, especially:
- distribution of dissolved components in nature waters
- acid-base systems
- carbonate systems
- oxidation/reduction systems
- origin and composition of lithogenic waters
- thermodynamic and kinetic models of rock-water system
- hydrologic cycles
- individual parts of hydrosphere (atmospheric water, surface water, groundwater, seawater).
Syllabus
  • Thermodynamics of rock-water systems: Thermodynamic functions. Dependencies of Gibbs' energy, entropy, and Gibbs' energy changes on reaction advancement. Quartz-water system. Distance from equilibrium. Saturation index.
  • Kinetics of processes in rock-water system: Rate constants, steady states, influences of temperature, mixing, and surface area, potential barrier, TST theory, dynamic equilibrium.
  • Chemical and physical properties of water: Water structure. Bonds, electronegativity, partial charges. Dissolution of solids. Dissolution of gasses (partial pressure, Henry's law, dependency of Henry's constant on temperature). Dissolution of O2, N2, CO2.
  • Forms of dissolved components: Homogeneous and heterogeneous systems, true and colloid solutions, suspensions. Simple ions, complexes, ion pairs, organic complexes.
  • Expression of concentrations: Activities. Standard states. Molar and weight concentrations, mg/l, ppm, ppb, mol/l, equivalents. Iont strength. Activity coefficients. Graphic expression of composition.
  • Acido-basic reactions: Water dissociation. pH, instrumentation, electrodes. Balances, electroneutrality. Salinity and alkalinity. Palmer's clasification.
  • Carbonate system: Carbon dioxide. Partial pressures. Carbonic acid. Dissociation. Carbonate species. Calcite dissolution. Equilibrium constants. Distribution coefficients. Closed and opened systems. Acido-basic titration. Buffering. Gran's titration.
  • Si, Al, Fe, Mn, Cu, Zn, Pb systems: Aqueous solutions, forms of species, distribution and stability as function of pH.
  • Oxidation and reduction: Gibbs' energy, Faraday's constant, electro-chemical potentials, Nernst's equation, redox potential, mixed potentials, electron activity. Instrumentation, electrodes, hydrogen electrode. Eh-pH diagrams. Fe, Mn, N, S systems.
  • Types, evolutions and classifications of natural waters:
  • Box-models (Reservoirs, fluxes, residence and response times, geologic and hydrologic cycles).
  • Atmospheric water (Resources, composition, pH, origin. Vapor tension, humidity, dew point. Aerosols, wet and dry deposition, precipitation, rainwater mineralization. Evaporation, transpiration, evapo-transpiration).
  • Surface waters (mass balances, catch area).
  • Sub-surface waters (Surface and sub-surface outflow, soil and subterranean water, un-saturated zone, hanged and buttressed capillary water, saturated zone, mineralization).
  • Seawater (Chemical and isotopic composition, origin, properties, steady states of individual elements. Carbonate compensation depth).
  • Lithogenic waters (Waters of acid aluminosilicate rocks. Waters of basic and ultrabasic rocks. Karst waters. Waters of sandstones and marlstones).
  • Other types of waters (Endogenous waters, fossil (juvenile) waters. Brackish waters. Pore waters. Metamorphic, volcanic, and magmatic waters. Mining waters. Waters of ores, slag heaps, and setting pits).
