Soil Acid Neutralizer

 · Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate. These are called dolomitic limestone and calcitic limestone respectively. The first thing that needs to be done is a soil test to see how acidic the soil actually is. You want your soil pH to be around 7.0, or neutral.

What Does Acid Rain Do to Limestone? | eHow

As acid rain falls to the earth''s surface, limestone rocks and limestone components in soil will react with the rain, neutralize the acid and dissolve. As the limestone dissolves, the rocks will wear away, becoming pitted with rounded edges. The dissolution process will change the appearance of the landscape as the rocks slowly wear away over time.

Limestone and Acid Rain

Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, H 2 CO 3, in the water.

Can you acid wash limestone?

Also asked, can you use muriatic acid to clean limestone? If you remember high school chemistry, limestone is calcium based and acids don''t mix well with calcium. If you use an acid (i.e., muriatic acid) to try cleaning your limestone patio you will end up with a chemical reaction similar to the old vinegar and baking soda volcanoes, which could really damage your patio.
