Naturally, limestone has a low solubility in water. However, water containing dissolved carbon dioxide produces carbonic acid according to the following reaction: H2O + CO2 = H2CO3. Carbonic acid is a weak acid, however, through time, it can significantly carve out limestone. Thus, carbon dioxide, which is present everywhere, play an important role in dissolving limestone.

If the concentration of sodium is greater outside a cell than inside the cell, which process could move sodium out of the cell?
Papessa [141]
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.<span>
