Sodium bicarbonate, with the molecular formula NaHCO?, is an inorganic compound that appears as a white powder or fine crystals. It is odorless, has a salty taste, is highly soluble in water, and its aqueous solution is slightly alkaline. It decomposes easily when heated and slowly breaks down in moist air, releasing carbon dioxide. Decomposition begins around 50°C and completes at 270°C^[1]. It vigorously decomposes upon contact with acids, producing carbon dioxide. Sodium bicarbonate is widely used in chemical, food, light industry, textile industries, as well as in daily life, and holds an important position in the national economy.
