Product Description
Sodium Bicarbonate is a white, odorless, crystalline powder with a slightly salty, alkaline taste. It is sparingly soluble in water, forming a clear, colorless solution with a mildly alkaline pH (typically 8.3–8.5 for a 1% solution). The compound is non-corrosive, stable under normal conditions, and acts as a gentle buffer, moderating pH changes. Its low alkalinity and non-toxic nature make it safe for use in food, pharmaceuticals, and environmental applications.

Application Sectors and Industries of Sodium Bicarbonate
Food Industry
Widely used as a leavening agent in baking, sodium bicarbonate reacts with acids to produce carbon dioxide, resulting in soft, fluffy baked goods. It also regulates acidity and preserves freshness in food products.
Pharmaceutical and Medical Industry
Used as an antacid to neutralize excess stomach acid, sodium bicarbonate is also administered in emergency medicine to correct metabolic acidosis and manage certain drug overdoses. It is a component in dialysis solutions and oral care products.
Environmental Applications
Sodium bicarbonate is utilized in flue gas treatment for air pollution control, particularly to remove sulfur dioxide (SO₂) from industrial emissions, supporting regulatory compliance and environmental protection.
Cleaning Products
Its mild abrasiveness and alkaline nature make it a staple in household and industrial cleaners. It removes stains, deodorizes, and acts as a gentle disinfectant. Sodium bicarbonate is also used in abrasive blasting for delicate surface cleaning.
Textile and Leather Industry
Balances pH during textile dyeing, ensuring color vibrancy and fabric quality. In leather processing, it neutralizes acids and softens hides, improving the feel and durability of finished products.
Fire Extinguishers
A key ingredient in dry chemical fire extinguishers, sodium bicarbonate releases CO₂ when heated, effectively suppressing small fires by displacing oxygen.
Agriculture and Animal Husbandry
Added to animal feed to balance pH in livestock stomachs, improving digestion and reducing acidosis. It is also used to adjust soil pH for optimal plant nutrient uptake.
Cosmetics and Personal Care
Found in toothpaste, deodorants, and exfoliants, sodium bicarbonate acts as a gentle abrasive and natural odor neutralizer, enhancing product performance and user comfort.
Chemical Industry
Used as a raw material in the production of sodium carbonate, effervescent tablets, and various specialty chemicals. It also acts as a buffer in laboratory and industrial processes.
Water Treatment
Helps neutralize acidic water and maintain stable pH levels in municipal and industrial water treatment systems, protecting infrastructure and improving water safety.
