Step-by-step explanation:
Ammonium sulfite and ammonium bisulfite are marketed as reducing agents in various industries.
They are commonly used in food processing to remove oxygen and prevent the oxidation of food. For example, ammonium sulfite is used in the production of wine to preserve its color and flavor. While ammonium bisulfite is used in the brewing industry to inhibit unwanted bacterial growth.
These compounds are also used in water treatment processes to remove dissolved oxygen and reduce the formation of scale and corrosion in pipes and equipment.
