what minerals are carbonate
Solubility: Of all the common carbonate minerals, calcium carbonate is most soluble. The solubility of CaCO 3 depends on the polymorph. At 25 degrees, the K sp for calcite and aragonite (the most common polymorphs of CaCO 3) are 10 -8.48 and 10 -8.34, respectively.Click here to see solubility product constants for other minerals.alcite is one of the most abundant of the non-silicate minerals. Pure calcium carbonate is colorless but, because it dissolves in acidic water and can recrystallize with different inclusions, calcite has many forms and colors in nature.
Some rocks contain carbonate minerals and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite.alcite and other carbonate minerals have a low resistance to weathering and can be attacked by acids in natural waters and soils. When testing material that has been exposed at Earth's surface it is very important to test unweathered material. A fresh surface can usually be obtained by breaking the rock.
