The sulfite process produces wood pulp that is almost pure cellulose fibers by treating wood chips with solutions of sulfite and bisulfite ions. These...

Sulfites or sulphites are compounds that contain the sulfite ion (systematic name: sulfate(IV) ion), SO2− 3. The sulfite ion is the conjugate base of bisulfite...
