Lithium sulfite, or lithium sulphite, is an inorganic compound with the chemical formula Li2SO3.
Preparation
Lithium sulfite can be prepared by treating lithium carbonate solution with sulfur dioxide.[2] The anhydrous form can be prepared by heating the hydrate under vacuum.[3]
It also occurs as a byproduct in the preparation of lithium sulfide from lithium hydroxide and sulfur.[4]
