Al2SO4316H2O

Al2SO4·31H2O, also known as aluminum sulfate monohydrate or copper sulfate pentahydrate, is a chemical compound with the formula Al2(SO4)3·31H2O. It is a salt composed of aluminum ions, sulfate ions, and water molecules.

The compound was first observed in nature as a mineral called alunite. It is found in a variety of geological formations and is often associated with copper deposits.

In the laboratory, Al2SO4·31H2O can be synthesized by dissolving aluminum hydroxide in sulfuric acid and then crystallizing the resulting solution. The resulting crystals are typically white or colorless.

Al2SO4·31H2O is a relatively stable compound and is not highly reactive. It is, however, soluble in water and can be used as a precursor to other aluminum compounds.

In addition to its use as a laboratory reagent, Al2SO4·31H2O has been found to have applications in the removal of pollutants from wastewater and in the production of zeolites and other ion exchange materials.

Toxicity of Al2SO4·31H2O has not been extensively studied, but its resemblance to other aluminum compounds suggests that it may have similar toxicity profiles. Handling of the compound should be in a well-ventilated area, and contact with skin and eyes should be avoided.

The compound has several commercial uses, including the production of batteries, water treatment, and as a component in adhesives and sealants. The exact nature of its commercial uses and applications is not well documented.
