Aragonite Saturation State of Seawater

Aragonite Saturation State of Seawater The precipitation and dissolution of aragonite in seawater can be described by the chemical reaction: Ca 2+ + CO 3 2-↔ CaCO 3 (1) where Ca 2+ is the dissolved concentration of calcium ions in seawater, CO 3 2-is the dissolved concentration of carbonate ...
