Sodium hydrogen carbonate is also known as sodium bicarbonate or baking soda because it decomposes on heating to generate bubbles of carbon dioxide (leaving pores in cakes or pastries and making them light and fluffy).
NaHCO3 is made by saturating a solution of sodium carbonate with carbon dioxide. The white crystalline powder of sodium hydrogen carbonate being less soluble gets separated.
On an industrial scale, sodium hydrogen carbonate (NaHCO3) is obtained as an intermediate product in Solvay process for the manufacture of sodium carbonate.
Sodium hydrogen carbonate is a white crystalline solid having a density of about 2.2 g/mL
It has alkaline taste and is sparingly soluble in water. The solubility of
sodium hydrogen carbonate increases with the rise of temperature
- As a component of baking powder
- In fire
extinguishers
- In medicines as a mild antiseptic for skin diseases
and to neutralize the acidity of stomach
- As a reagent in laboratory
