FAQ

What are the physical and chemical properties of Sodium hydrogen carbonate (CAS: 144-55-8)?

Sodium hydrogen carbonate, also known as sodium bicarbonate, has a white, crystalline appearance with a molecular weight of approximately 84.01 g/mol. It is slightly soluble in water, with a solubility of about 1.02 g/100 mL at 25°C. Chemically, it reacts readily with acids to produce carbon dioxide gas, making it useful in various applications such as baking, cleaning, and as a pH regulator.

How is Sodium hydrogen carbonate (CAS: 144-55-8) typically synthesized?

Sodium hydrogen carbonate can be synthesized by the reaction of sodium carbonate with carbon dioxide in the presence of water. The chemical equation for this reaction is: Na2CO3 + CO2 + H2O → 2NaHCO3. This method yields a high purity product with good selectivity and reasonable yield.

What industries use Sodium hydrogen carbonate (CAS: 144-55-8)?

Sodium hydrogen carbonate is widely used in various industries including pharmaceuticals for buffering solutions and effervescent tablets, polymers for neutralizing acidic catalysts, and food and beverages for baking and flavoring. It also finds applications in the manufacturing of detergents, cleaning products, and as a fire extinguishing agent.

What precautions should be taken when handling Sodium hydrogen carbonate (CAS: 144-55-8)?

When handling sodium hydrogen carbonate, it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store in a cool, dry place away from direct sunlight and heat sources. In case of a spill, sweep up the powder and dispose of it according to local regulations. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information.
