Introduction
Sodium bicarbonate (NaHCO₃), with the molecular formula NaHCO₃, is an inorganic compound, white powder or fine crystals, odorless, salty, easily soluble in water, slightly soluble in ethanol (some say insoluble), and its aqueous solution is slightly alkaline. It is easily decomposed by heat, and slowly decomposes in humid air to produce carbon dioxide. It begins to decompose at about 50°C and completely decomposes when heated to 270°C [1]. It decomposes strongly in the presence of acid to produce carbon dioxide. Sodium bicarbonate is widely used in chemical, pharmaceutical, food, light industry, textile and other industrial fields as well as in people's daily life, and occupies an important position in the national economy.
