AlNO336H2O

AlNO336H2O refers to aluminum nitrate nonahydrate. It is the hydrated salt of aluminum and nitric acid. The chemical formula indicates that for every aluminum cation (Al3+) and three nitrate anions (NO3-), there are nine water molecules (H2O) associated with the crystal structure. This compound typically appears as white crystalline solid. It is soluble in water and slightly soluble in alcohol. Aluminum nitrate nonahydrate is generally prepared by reacting aluminum hydroxide or aluminum metal with nitric acid. The reaction produces aluminum nitrate and water. Upon evaporation of the solution, the nonahydrate form crystallizes out. This compound finds applications in various fields, including as a mordant in dyeing textiles, in the preparation of catalysts, and as a corrosion inhibitor. It can also be used in leather tanning processes and in the production of alumina. While generally considered to be of low toxicity, it is still advisable to handle it with care, avoiding contact with skin and eyes, and ensuring adequate ventilation. Decomposition upon heating can release toxic nitrogen oxides.
