Formation of Sodium Chloride

2Na + Cl2 → 2NaCl

Обзор

Sodium metal reacts vigorously with chlorine gas to form sodium chloride, common table salt. This is a classic example of an ionic compound formation where a metal transfers electrons to a nonmetal. The reaction is highly exothermic, producing a bright yellow flame.

Пример из жизни

Table salt used in cooking is produced commercially through mining or evaporation of seawater, though the direct synthesis from elements demonstrates ionic bond formation.

Промышленное значение

Sodium chloride production is a massive global industry supporting food preservation, water treatment, and as a feedstock for chlor-alkali processes producing chlorine and sodium hydroxide.
