Beryllium sulfite would have the formula of
[Be(OH)]2SO3 and the molecular weight of 132.0824 g/
mol. It could be prepared by the reaction of a magnesium
hydroxide slurry and SO2 gas:
Be(OH)2+SO2(gas)+H2O→BeSO3·6H2O
No article on “beryllium sulfite” can be found in the
scientific literature. There is no scientific data that beryllium sulfite even exists as no studies have documented such a salt. The same may be said for the compound “beryllium bisulfite”.
