natriumhydrogen

Natriumhydrogen, also known as sodium bicarbonate or baking soda, is a chemical compound with the formula NaHCO₃. It is a white crystalline solid, often found in powder form, and is an amphoteric salt, meaning it can act as both an acid and a base. In aqueous solution, it partially dissociates into sodium ions (Na⁺) and bicarbonate ions (HCO₃⁻).

Natriumhydrogen is a common ingredient in household products. Its leavening properties are widely utilized in baking, where it reacts with acids to produce carbon dioxide gas, causing doughs and batters to rise. It is also used as a mild abrasive and deodorizer in cleaning products. In medicine, it is sometimes used as an antacid to neutralize stomach acid and as a component in treatments for certain medical conditions.

The production of natriumhydrogen typically involves the Solvay process, which uses sodium chloride, ammonia, and carbon dioxide as primary raw materials. It is a relatively inexpensive and widely available compound. Its applications extend beyond domestic use, including in fire extinguishers, where it releases carbon dioxide to smother flames, and in some industrial processes.
