Determine on what factors and how the equilibrium concentration of CO2 depends on the system solid carbonate residue - water

- carbon dioxide The equilibrium concentration of CO2 in a system of solid carbonate residue and water is determined by the degree of solubility of the carbonates. The solubility of carbonates is affected by temperature, pressure, and the presence of other compounds (such as HCO3- and CO32-) and ions in solution. In general, as temperature and pressure increase, the solubility of the carbonates increases. Additionally, the presence of other compounds and ions in solution may either decrease or increase the solubility of carbonates. As the solubility of the carbonates increases, the equilibrium concentration of CO2 in solution increases.
