Sodium bicarbonate is an inorganic salt. In 1791, the French chemist Nicholas Lebens produced sodium bicarbonate in its present form. Sodium bicarbonate for baking bread and leather. The ingestion of sodium bicarbonate is harmless unless it is too high.

Baking soda or sodium bicarbonate is one of the sodium salts in combination with carbonic acid, which is just one acid hydroxide of this compound with sodium. This combination is a bit odorless and flavorful, which is a bit of gaming and is white or crystalline powder. Bicarbonate is also an absorbent of moisture and deodorant. This compound, which is named after its popular name, is sometimes used as a baking soda for baking dough, and sometimes used to reduce gastric acid and burn it. Sodium bicarbonate in its structure has an anionic group of HCO3 and a Na + cationic agent. Sodium bicarbonate is found naturally in the form of Nahcolite. Ancient Egyptians used a natural form of the alkaline salt, including sodium carbonate decahydrate and sodium bicarbonate. They used this alkaline salt as a washable soap. In 1791, the French chemist Nicholas Lebens produced sodium bicarbonate in its present form.John Dwight of Massachusetts and his brother-in-law, Austin Church have built the first cookware plant from sodium bicarbonate and carbon dioxide.

Sodium bicarbonate is further produced by a salty process, which is the same reaction as sodium chloride, ammonia, and carbon dioxide in water, which results in the sodium bicarbonate obtained as a precipitate after being strained and heated to dry carbon dioxide. Sugar bake is processed annually by about 100,000 tons (2001). It is also possible to obtain sodium bicarbonate in the form of precipitated deposition by passing gas from a pure sodium carbonate solution or a sodium hydroxide solution into the solution.
Swallowing this substance is harmless unless it is too high. Smelling it may cause burning of the nose or throat. Contact with sensitive skin may cause itching or irritation of the skin. Contact with eyes may cause burns and redness in the eye.
