What is the chemical name of baking soda ?

Baking soda is the common name for the chemical compound sodium bicarbonate, which has the chemical formula NaHCO3 [t2][t4]. It is also frequently referred to as sodium hydrogen carbonate [c1][t1]. This substance is a monosodium salt of carbonic acid and is characterized as a mild alkaline compound [t2][t7]. In culinary applications, it is used as a leavening agent because it releases carbon dioxide gas when heated or reacted with an acid, causing dough to rise [c1][c3]. Other options provided are distinct chemicals: calcium carbonate is found in limestone, sodium chloride is common table salt [c4], and potassium permanganate is a strong oxidizing agent. Sodium bicarbonate is industrially produced via the Solvay process or by treating sodium carbonate with carbon dioxide [t1][t6].
