Manufacturing 
  
When introducing carbon dioxide into a saturated and cooled soda solution, sodium hydrogen carbonate is obtained:

N / A2CO3 + CO2 + H2O 2 NaHCO3   
   
After filtration, the product must be carefully dried so that it does not disintegrate again. Sodium hydrogen carbonate is also formed when carbon dioxide is introduced into caustic soda and as an intermediate product in soda production using the Solvay process.
    
  
use 
  
Sodium hydrogen carbonate is often used in foods as a raising agent and in effervescent powders. There is a mixture of baking soda with a solid acid like citric acid. But it also occurs in bath tablets and fire extinguishing powders. In medicine, sodium hydrogen carbonate is suitable as an antacid against acidity in the stomach; It is also used to soften water.
