The compound with the formula AlHSO33 is not a valid chemical compound. Here's why:

* Aluminum (Al) forms a +3 charge when it becomes an ion.

* Hydrogen Sulfite (HSO3) forms a -1 charge when it becomes an ion.

To balance the charges, we need 3 hydrogen sulfite ions for every aluminum ion. The correct formula for the compound is Al(HSO3)3.

This compound is called Aluminum bisulfite.
