NaAlOH4
NaAlOH4 is the chemical formula for sodium tetrahydroxoaluminate. It is an inorganic compound. This compound is a salt of the tetrahydroxoaluminate anion, [Al(OH)4]−, and the sodium cation, Na+. It is often encountered as a white, amorphous solid. NaAlOH4 is soluble in water, where it dissociates into sodium ions and tetrahydroxoaluminate ions. The tetrahydroxoaluminate ion itself is a Lewis acid-base adduct, where the aluminum(III) ion is coordinated by four hydroxide ligands. This coordination provides stability to the aluminum in an aqueous environment, preventing the precipitation of aluminum hydroxide under certain conditions. NaAlOH4 can be synthesized through various methods, often involving the reaction of aluminum metal or aluminum compounds with sodium hydroxide in aqueous solution. It has found applications in areas such as water treatment, where it can act as a flocculant, and in the synthesis of other aluminum-containing materials. The compound's properties are influenced by the pH of the solution.
