Na2Al2Si4O122H2O

Na2Al2Si4O122H2O is the chemical formula for a hydrated sodium aluminum silicate. This compound belongs to the zeolite group of minerals, characterized by their complex three-dimensional framework structures composed of interconnected aluminum and silicon tetrahedra. The presence of water molecules within these frameworks is a defining feature of hydrated zeolites. The specific arrangement of these tetrahedra in Na2Al2Si4O122H2O creates channels and cavities capable of trapping and exchanging cations, such as sodium ions, and water molecules. The formula indicates a molar ratio of two sodium atoms, two aluminum atoms, four silicon atoms, and twelve oxygen atoms, along with twenty-two water molecules. The systematic name for minerals with this specific framework and composition can vary depending on crystallographic studies and nomenclature conventions within mineralogy. These types of compounds are often found in volcanic rocks and sedimentary environments. Their unique structural properties lend themselves to various applications, particularly in areas like ion exchange, adsorption, and catalysis, though specific applications are highly dependent on the precise mineral structure.
