Sodium Bisulfite

Sodium Bisulfite (NaHSO3) is a corrosive, strong reducing agent chemical liquid with a faint sulfurous odor. It is used in food processing and in the manufacture of other chemicals. Even though it is not flammable, we still recommend a secure chemical storage building or container that meets specific regulations for storing Sodium Bisulfite. That’s why we suggest one of the following: View All Chemical Storage Products
