Several very different but related processes control the precipitation of CaCO in natural aqueous systems.

An aqueous system is uniquely defined by its chemical composition, temperature, and pressure.

C is a key parameter when making measurements related to the pH of natural aqueous systems, and carbon dioxide flux estimates.

The solvated electrons can be scavenged from both aqueous and organic systems with nitrobenzene or sulfur hexafluoride.

For ease in handling and because biological systems are in aqueous systems, good solubility in water was required.

The latter value is frequently used for aqueous systems.

Its utility comes from its ability to stabilize emulsions of nonpolar materials in aqueous systems.

These catalysts are stable in water, so avoid the need for organic solvents; some reaction rates are even enhanced by aqueous systems.

This model is valid for most aqueous systems because the Debye length is only a few nanometers there.

This separation was done using an aqueous two-phase system of dextran-polyethylene glycol-water to stabilize the amino acids.
