Changing pH in Soil

a soil test indicates a pH below , the usual recommendation is for the application of ground limestone. In addition to having the ability to raise pH, limestone contains calcium. Some prefer dolomitic limestone because it contains both calcium and magnesium, however soils high in magnesium (serpentine) do not need more magnesium.

Calcium carbonate Essential Chemical Industry

Very fine and pure calcium carbonate is used as filler in plastics and paper. A filler is a substance that gives bulk but does not alter the properties of the substance to which it is added and is also inert. Calcium carbonate when very finely crushed (less than 2 microns) is used in paints to give a 'matt' finish. Figure 8 Uses of limestone.

What happens when acid reacts with limestone? | Questions ...

Jun 15, 2008· Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
