Lime or calcium carbonate's reaction with an acidic soil is described in figure 1, which shows acidity (H) on the surface of the soil particles. As lime dissolves in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidity reacts with the carbonate (CO 3) to form carbon dioxide (CO 2) and water (H 2 O).
