Aluminium sulphite
Description
Aluminium sulphite is an inorganic compound with the formula
A
l

)
3
Al

)
3
, composed of aluminium ions and sulfite ions. It is much rarer and less commonly encountered than aluminium sulphate or sulphide, and is typically referenced in chemical literature, synthesis, or as a theoretical intermediate rather than a widely available reagent.
Key Properties

) ions.
Solubility: Expected to be soluble in water, forming mildly acidic solutions.
Not typically available as a pure solid or commercial reagent; often studied or prepared for chemical research.
Preparation and Occurrence
Aluminium sulphite can be produced through the reaction of aluminium salts with sulfite sources, though it is prone to oxidation in the presence of air, resulting in conversion to aluminium sulphate (

). This limits its stability and practical uses.
Applications
Mainly of chemical interest in laboratory synthesis or for study of reactions involving sulphite ions.
No widespread industrial or commercial applications, unlike aluminium sulphate.
Availability
Aluminium sulphite is rarely available from standard chemical suppliers, focusing instead on more stable sulphate or sulphide compounds. Some specialty chemical distributors may list it for laboratory research or custom synthesis in small quantities.
For most industrial and laboratory needs, aluminium sulphate (

) is preferred due to its stability and wide range of applications, including water treatment, paper manufacturing, and analytical chemistry.
