Sodium Hydrogen Carbonate Extra Pure, commonly known as baking soda, is a white, odorless, water-soluble crystalline powder with the formula NaHCO₃. It is widely used in laboratory and industrial settings as a mild alkaline reagent and buffering agent. In the food industry, it serves as a leavening and acidity regulator agent, while in pharmaceuticals, it is used for antacid formulations. Its ability to neutralize acids and release carbon dioxide under heat makes it valuable in baking, water treatment, and cleaning applications. The Extra Pure grade guarantees high purity and suitability for analytical, pharmaceutical, and food-grade uses. It should be stored in dry, sealed containers to maintain quality and prevent caking.
