Description
Sodium bicarbonate is commonly used in fields such as food, pharmaceuticals and households; the production activity of this product is the weighted average of the Hou's soda process and the double decomposition process; if you cannot specify the particular production process of sodium bicarbonate, you can use this dataset, and detailed information such as technical details and boundary scope can refer to the datasets of the various production processes of sodium bicarbonate; infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary.
Activity Description
The production activities for this product are a weighted average of the metathesis method and the soda ash method.
Process Description
Sodium bicarbonate (CAS number 144-55-8) is a white crystalline powder with the chemical formula NaHCO3, commonly known as baking soda. It is stable at ambient temperature but gradually decomposes above 50°C to form sodium carbonate, water, and carbon dioxide. It is readily soluble in water and forms a mildly alkaline solution. Its vigorous reaction with acids releases carbon dioxide, making it a common raw material for leavening agents and fire-extinguishing agents. In the food industry, it is widely used to leaven baked goods such as bread and biscuits. It is also used as an antacid in pharmaceuticals and for household cleaning and deodorizing.
