There is a great variety of the pH and buffers in the environment. Acid rain as the result of industrial produced sulfur and nitrogen compounds leading to sulfuric and nitric acid, can cause damage to farm and woodlands and the growth of plants will be greatly hindered. The pH of neutral soil varies from 6.6 to 7.3. H₂CO₃ is the most important source for H⁺-ions and carbonate-containing buffers keep the pH constant for a long time [1]. Forest liming, which is the application of calcium- and magnesium-rich carbonate, is performed to fight acidification and to increase buffer capacity.
