Uses of Sodium Hydrogen Sulphite

Synthesis of Sulfite and Bisulfite Salts:

As mentioned earlier, sodium hydrogen sulfite can act as a starting material for the preparation of various sulfite and bisulfite salts. These salts have various applications in research and industry, and sodium hydrogen sulfite provides a convenient way to generate them. For instance, it can be used to synthesize sodium sulfite (Na2SO3) through a reaction with sodium hydroxide (NaOH).

Reagent in Specific Analytical Reactions:

In some analytical chemistry techniques, sodium hydrogen sulfite might be employed as a reducing agent. Reducing agents participate in reactions by donating electrons to another compound, and sodium hydrogen sulfite can facilitate specific reactions in this manner. However, it’s important to note that there might be other, more common reducing agents preferred for many analytical procedures due to factors like selectivity of reaction rates.

Research on its Properties:

Of course, sodium hydrogen sulfite itself can be the subject of laboratory research. Scientists might study its chemical behavior, reactivity with other compounds, or potential applications in new areas.
