Stable solid and aqueous H2CO3 from CO2 and H2O at high pressure and high temperature
Carbonic acid (H2CO3) forms in small amounts when CO2 dissolves in H2O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H2CO3 plays an important role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study o...
متن کاملHydration state and activity of aqueous silica in H2O-CO2 fluids at high pressure and temperature
Quartz solubility in H2O-CO2 fluids was measured at 800 °C and 10 kbar. Mixed fluids were generated from hydrous oxalic acid, silver oxalate, silver carbonate, and liquid H2O; solubility was determined by weight changes of the quartz crystals. Stringent blank tests and weighing procedures were used to establish the CO2 and H2O contents of experimental fluids. Using experimentally constrained mo...
متن کاملDimerization of CO2 at high pressure and temperature.
Understanding the behavior of simple molecular systems under the combined effect of high pressure (P) and temperature (T) has important implications in the modeling of planetary interiors, in the chemistry of detonation, and in the synthesis of new materials. Extreme conditions of P and T can be partially accessed in the laboratory either in heated diamond-anvil cells or in shock wave experimen...
متن کاملThe solubility of fluorite in H2O and H2O–NaCl at high pressure and temperature
The solubility of fluorite in H2O and H2O–NaCl has been measured at 600–1000 °C, 0.5–2.0 GPa in a piston–cylinder apparatus. Fluorite dissolves congruently at all conditions investigated. The data indicate that the concentration of fluorite dissolved in H2O is low at 600 °C and 0.5 GPa (0.0014 mol/kg H2O) but increases strongly with temperature (T) and pressure (P) to 0.247 mol/kg H2O at 1000 °...
متن کاملCorrespondence: Reply to ‘Strongly-driven Re+CO2 redox reaction at high-pressure and high-temperature'
Santamaria-Perez et al.1 attempt to reproduce our CO2–SiO2 solid solution2. In their study1, mixtures of CO2 and SiO2 similar to those studied in our work2 were indirectly laser heated up to 2,400K and 50GPa by using Re as an internal heater, and a CO2–SiO2 solid solution was not obtained. Instead, the only temperature quenched crystalline phases identified by X-ray diffraction were: known poly...
