Summary
Calculated models of the chemistry of natural waters show how mass is distributed among aqueous species, minerals, and gases, whether individual minerals are undersaturated or supersaturated, and gas partial pressures within the waters. This chapter explores how to construct and interpret computed models of water chemistry, using seawater, river water, and deep-sea brines as examples.
