AlNO6HO

AlNO6HO is a chemical formula that represents aluminum nitrate hexahydrate. It is the hydrated salt of aluminum nitrate. In this compound, aluminum is bonded to nitrate ions, and each formula unit is associated with six molecules of water. The chemical formula can be more accurately written as Al(NO3)3·6H2O, explicitly showing the aluminum cation and the nitrate anion, along with the water of crystallization.

Aluminum nitrate hexahydrate typically appears as a crystalline solid. It is soluble in water and can also dissolve in some organic solvents. This compound finds applications in various industrial processes. For instance, it is used in the textile industry as an astringent and in leather tanning. It can also serve as a precursor for the synthesis of other aluminum compounds. In laboratory settings, it might be used as a reagent in certain chemical reactions or for educational purposes to demonstrate hydration and salt properties.

The preparation of aluminum nitrate hexahydrate usually involves reacting aluminum hydroxide or aluminum oxide with nitric acid. The resulting solution is then evaporated and cooled to crystallize the hexahydrate form. Care must be taken during handling as it can be irritating. When heated, aluminum nitrate hexahydrate loses its water of crystallization, eventually decomposing into aluminum oxide and nitrogen oxides at higher temperatures.
