Question

What is the common name for $N{{a}_{2}}S{{O}_{3}}$?

Answer 1

A nonsystematic name for a chemical compound is known as a trivial name in chemistry. That is, according to the norms of any formal system of chemical nomenclature, such as IUPAC inorganic, the term is not accepted. A common name is called a trivial name since it is not a formal name.

Complete answer:
In most cases, trivial names are ineffective in describing the fundamental characteristics of the item being named. The molecular structure of a chemical molecule, for example, is not indicated. Furthermore, in certain situations, innocuous names might be confusing or have various meanings in different sectors or geographical locations.
The common name is the term we use in everyday life, whereas the IUPAC name fulfils the chemical standards for designating a compound. Organic compounds are called after the parent hydrocarbon using prefixes or suffixes to indicate the presence of a functional group in IUPAC nomenclature.
Sodium sulphite ($N{{a}_{2}}S{{O}_{3}}$) is a crystalline solid that is white in colour and has a sulphurous, salty flavour. When heated, it decomposes. It's commonly found in powder, crystalline, and tablet form. Another dechlorinating chemical frequently used by utilities is sodium sulphite. It's usually offered as a powder. In addition, several businesses produce in tablet form. The natural state of sodium sulphite is somewhat alkaline. As a reducing agent, sodium sulphite is said to scavenge more oxygen than sodium thiosulfate.
The inorganic salt sodium sulphite ($N{{a}_{2}}S{{O}_{3}}$) has the chemical formula $N{{a}_{2}}S{{O}_{3}}$. Two sodium cations ($N{{a}^{+}}$) and one sulfide anion make up this ionic molecule ($S{{O}_{3}}^{2-}$). A saturated sodium sulphite solution in water is moderately basic, with a pH of about 9. Crystallization of such a solution can produce $N{{a}_{2}}S{{O}_{3}}$ heptahydrate crystals.

Note:
The sodium cations and the sulfate anion form two ionic connections in a sodium sulphite molecule. Each sodium ion has a positive charge. The -2 charge on the sulphite ion, on the other hand, is delocalized by resonance, resulting in a partial charge of $-\dfrac{2}{3}$ on each oxygen atom. The total charge on a molecule of $N{{a}_{2}}S{{O}_{3}}$ is zero.
