3. Paper and Pulp Industry The paper and pulp sector also utilizes sodium metabisulfite as a bleaching agent. Its ability to reduce sulfur compounds aids in the decolorization process, leading to brighter and cleaner paper products.
Conclusion
Concentrated glacial acetic acid has a molecular formula of C2H4O2 and is characterized by its carboxylic acid functional group. This compound possesses a high boiling point (about 118 degrees Celsius) and a low vapor pressure, which makes it less volatile compared to other organic solvents. Its miscibility with water allows it to form a variety of solutions, but extreme caution is advised as it reacts violently with strong oxidizers and can release harmful gases under certain conditions.
The environmental impact of potassium metabisulfite is another consideration. Although it is a synthetic compound, it is biodegradable and breaks down into harmless byproducts when used in appropriate amounts. This makes it a relatively environmentally friendly option compared to some synthetic preservatives.
