Carbonate System

(system governing water and CO2 in the presence of each other)

The Carbonate System is a system of chemical reactions and their characteristics that determine the equilibrium of the chemistry resulting from water and CO2 in each others presence given a certain Temperature and pressure.

Water and Carbon (C) Dioxide react to each other to create Carbonic Acid (H2CO3) which dissociates into a Hydrogen (H) ion and Bicarbonate (HCO3) which dissociates into a hydrogen ion and carbonate (CO3). When sufficient of these chemicals are created to balance them with the opposite reactions, a balance is obtained. This determines the Acidity (pH) of such water, which includes any water in the presence of the Earth's Atmosphere such as oceans, lakes, etc.
