WebChemical Compound Inorganic Chemistry. Aluminium nitrate is a white, water-soluble compound of aluminum and nitric acid that is most usually found as the crystalline hydrate, Al (NO 3) 3 •9H 2 O. It is a water-soluble salt of nitric acid and aluminum. It has a white color to it. This substance can be found as a crystalline solid or as a powder.
A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures. Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the composition without indicating how the water is bound. Per IUPAC's recommendations, the middle dot is not surrounded by spaces when indicating a chem… WebSpecifically, the crystalline active pharmaceutical agent naproxen sodium, and its hydrates, is studied in silico using density functional theory and molecular dynamics, ultimately elucidating the face-specific dehydration …
