Reactivity and uses
Sodium bisulfite is a common industrial reducing agent, as it readily reacts with dissolved oxygen:
 * 2 NaHSO3 + O2 → 2 NaHSO4

It is usually added to large piping systems to prevent oxidative corrosion. In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor.

It is used for preserving food and beverages.

Organic chemists can purify ketones or aldehydes using Sodium bisulfite. An impure solution is mixed with saturated aqueous sodium bisulfite in an ice bath, which after reacting will produce a crystalline solid. This solid can then be converted back to the original compounds using dilute acid or base. This happens due to the reversible nature of nucleophillic addition to carbonyl groups.
