Calcium carbonate ka sutra

Calcium carbonate is the principal mineral component of limestone. Its chemical and physical properties lie behind the modern-day uses of limestone as well as the unique limestone landscapes of the countryside. Calcium carbonate – mineral forms The principal mineral component of limestone is a crystalline form of calcium carbonate known as calcite. Although calcite crystals belong to the trigonal crystal system, shown below, a wide variety of crystal shapes are found. Single calcite crystals display an optical property called birefringence (double refraction). This strong birefringence causes objects viewed through a clear piece of calcite to appear doubled. Another mineral form of calcium carbonate is called aragonite. Its crystal lattice differs from that of calcite, resulting in a different crystal shape – an orthorhombic system with needle-shaped crystals. Solubility Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites. Rainwater is weakly acidic, and when it meets with l...

Calcium carbonate is a chemical inorganic compound having the chemical formula CaCO 3 .It is also one of the most popular chemicals which is encountered first in school classrooms, where the use of chalk (which is a form of CaCO 3 ) is found. It is found in the crust of the earth. It is available in various forms, such as limestone, marble, and more. Although they are available in different forms, they are chemically similar and differ only physically. They are also called calcite. The symbol of calcium carbonate can be given as CaCO 3 . Types of Calcium Carbonate found in the Environment Calcium carbonate is present in three polymorphic forms - calcite, aragonite and vaterite. Calcite: It is the most stable and the least soluble. A rock-forming mineral, it is commonly found in sedimentary, metamorphic, and igneous rocks. Calcite is a common constituent of sedimentary rocks like limestone and marble. It is used extensively in construction material, agricultural soil treatment, pharmaceuticals and many more areas. Argonite: It is less stable and more soluble than calcite. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. Aragonite provides ingredients to sea life, and also maintains the pH levels to its natural level. It is used to remove pollutants like Vaterite: Hexagonal in shape, vaterite, is less stable than calcite and aragonite, with a higher solubility. It is found naturally in springs, organic tissue...
