Answer 1

Answer:

Carbonation (pH 7.5–9.0): The increase in the concentration of carbonate ions leads to the saturation of the system with CaCO3 with subsequent precipitation of CaCO3 (equilibrium pH 8.2) and other carbonates (e.g., with Mg, Na) at higher pH values. While this is not a weathering reaction per-se, the presence of CaCO3 in the system has a strong influence on the weathering rate of silicate minerals, as it buffers the solution pH near a value of 8, thus slowing down silicate weathering. At this stage, there is barely any Al in solution and conditions are such that the neoformation of smectites is favored (pH < 9.0). At higher pH values (see alkalinolysis) dissolution of aluminosilicates is accelerated.
