Give the name for NaHSO3. sodium bisulfite
The correct answer and explanation is:
The correct name for NaHSO₃ is sodium bisulfite.
Sodium bisulfite is a chemical compound that consists of a sodium cation (Na⁺) and a bisulfite anion (HSO₃⁻). The bisulfite anion is derived from sulfurous acid (H₂SO₃), where one hydrogen ion (H⁺) is replaced by a sodium ion (Na⁺), resulting in the formation of NaHSO₃.
Sodium bisulfite is a commonly used compound in various chemical and industrial applications. It can act as a reducing agent, which makes it useful in the bleaching and preservation of foods, particularly in the production of dried fruits and wines. It is also employed in water treatment processes to remove chlorine from water and is a key ingredient in some photographic developers.
In terms of structure, sodium bisulfite contains one sulfur atom, three oxygen atoms, and one hydrogen atom bonded to a sodium ion. This gives it a molecular weight of approximately 104.1 g/mol. The compound is usually available as a white crystalline solid that is soluble in water.
In its solid form, sodium bisulfite can release sulfur dioxide (SO₂) gas when exposed to acids or when heated, which can be hazardous in confined spaces. The compound should be handled with care to avoid inhalation of SO₂ fumes, which can be irritating to the respiratory system. Additionally, as a bisulfite, it can act as an intermediate in sulfur-containing reactions, playing a role in both reducing and oxidizing processes.
Understanding sodium bisulfite and its properties is crucial for industries that rely on sulfur-based compounds for various chemical transformations, food preservation, and water treatment.
