Abstract:
The classical influences of physical parameters and mixing corrosion are presented to study the equilibrium of the water-air-limestone chemical system. The frequent observation of cave levels in the mountain karstic systems is often associated with the greater facility of dissolution, near the water table. Some chemical mechanisms are analysed to show the greater karst corrosion on this level. Increased air pressure induces an increase in the saturation pCO2 of the water. Two confinement coefficients are used to analyse the role of a limited quantity of air in contact with water. The first (k) is the water mass / water + air mass ratio, the second (kn) is the mass of CO2 in water / mass of CO2 in water and air ratio. These two ratios show that the latter coefficient varies with air pressure, but is proportional to the varying pCO2.
