How do u derive a general formula (without undue approximations) to calculate the solubility of CaCO3(s) in a aqueous solution at any pH?
Thanks
Thanks
The general formula for Calcium carbonate is CaCO3.
Calcium carbonate is commonly used as a dietary supplement for the prevention of osteoporosis and as an antacid for treating heartburn. It is also used in the production of paper, paints, plastics, and as a filler for cosmetics and medications.
The chemical structure of Calcium carbonate is composed of one calcium atom, one carbon atom, and three oxygen atoms, with a molecular weight of 100.09 g/mol. It has a trigonal planar structure with a central carbon atom bonded to three oxygen atoms and a calcium atom bonded to the central carbon atom.
Calcium carbonate is a white, odorless, tasteless powder that is insoluble in water. It has a melting point of 1,339 °C and a boiling point of 825 °C. It is relatively soft with a Mohs hardness of 3, and has a density of 2.71 g/cm3.
Calcium carbonate is formed in nature through a variety of processes, including the deposition of marine organisms such as coral and shells, precipitation from water containing dissolved calcium and carbonate ions, and the metamorphism of sedimentary carbonate rocks.
