Products Description of Sodium Bicarbonate CAS#144-55-8
Sodium bicarbonate, widely known as baking soda, is a white, odorless crystalline solid with mild alkaline properties. It occurs naturally as the mineral nahcolite, a name derived from its chemical composition, NaHCO₃, by replacing the numerical “3” with the suffix “-lite.”

Product Application of Sodium Bicarbonate CAS#144-55-8
Sodium bicarbonate has a wide range of applications due to its mild abrasive properties and excellent acid-neutralizing ability. It is commonly used in cooking, cleaning products, and personal care formulations. In addition, sodium bicarbonate is an essential ingredient in effervescent products, where it reacts with acids to release carbon dioxide, producing a foaming effect. These versatile properties make it valuable in both household and industrial applications.
