What Is Sodium Bicarbonate?
Sodium Bicarbonate (NaHCO₃), also known as Baking Soda, Bicarbonate of Soda, or Sodium Hydrogen Carbonate, is a mild alkaline inorganic salt. It appears as a white, odorless crystalline powder that is freely soluble in water, producing a mildly alkaline solution (pH ~8.3 at 1%). It decomposes upon heating above ~50°C, releasing carbon dioxide (CO₂) and water — a property that makes it an effective leavening agent in baking and a reactive agent in flue gas treatment.
Sodium bicarbonate is closely related to Soda Ash (Sodium Carbonate, Na₂CO₃) but is significantly milder and safer to handle. It is produced industrially by the Solvay process (carbonation of sodium carbonate solution) or by direct carbonation of sodium hydroxide. China is one of the world's largest producers of sodium bicarbonate.

Sodium Bicarbonate vs. Soda Ash vs. Caustic Soda — Key Differences
Sodium Bicarbonate (NaHCO₃, pH ~8.3): Mildest alkalinity. Decomposes with heat releasing CO₂. Safe for food, feed, and pharmaceutical use. Used for leavening, flue gas treatment, and antacids.
Soda Ash / Sodium Carbonate (Na₂CO₃, pH ~11.5): Moderate alkalinity. Stable to heat. Used in glass manufacturing, detergents, and water treatment. Not suitable for direct food use at high concentrations.
Caustic Soda / Sodium Hydroxide (NaOH, pH ~14): Strongest alkalinity. Highly corrosive. Used in chemical manufacturing, pulp and paper, and soap making. Requires strict safety precautions.
Applications of Sodium Bicarbonate
1. Food Industry — Leavening Agent (E500ii)
Food-grade sodium bicarbonate (E500ii) is the classic chemical leavening agent in baking. When heated or combined with an acid (cream of tartar, buttermilk, vinegar), it releases CO₂ gas, causing dough and batter to rise. Key food applications:
Bread, cakes, biscuits, and cookies: Primary leavening agent in quick breads and baked goods not using yeast
Baking powder component: Combined with an acid (cream of tartar or sodium aluminum sulfate) and a starch to form baking powder
Noodle and pasta production: Used in alkaline noodle production (e.g., ramen) to improve texture, color, and flavor
Meat processing: Used as a tenderizer and pH adjuster in meat marination
Beverage carbonation: Used in effervescent tablets and powdered drink mixes
Cocoa processing (Dutch process): Used to alkalize cocoa powder, reducing acidity and darkening color
2. Flue Gas Desulfurization (FGD) — Environmental Protection
Industrial-grade sodium bicarbonate is one of the most effective dry sorbents for flue gas desulfurization (FGD) and acid gas removal in industrial emissions control. When injected as a fine powder into hot flue gas streams, it decomposes and reacts with SO₂, HCl, and HF:
SO₂ removal: 2NaHCO₃ + SO₂ → Na₂SO₃ + H₂O + 2CO₂ (and further oxidation to Na₂SO₄)
HCl removal: NaHCO₃ + HCl → NaCl + H₂O + CO₂
HF removal: NaHCO₃ + HF → NaF + H₂O + CO₂
Advantages of sodium bicarbonate for FGD include: high reactivity (especially when thermally activated), no wastewater generation (dry process), simple operation, and suitability for retrofitting existing plants. It is widely used in waste incineration plants, cement kilns, glass furnaces, and coal-fired power plants.
3. Animal Feed — Rumen Buffer & Feed Additive
Feed-grade sodium bicarbonate is widely used as a rumen buffer and feed additive in dairy cattle, beef cattle, and poultry nutrition:
Rumen pH buffering in dairy cows: High-grain diets produce excess lactic acid in the rumen, causing subacute ruminal acidosis (SARA) — a major cause of reduced milk production and health problems. Sodium bicarbonate buffers rumen pH, maintaining optimal conditions for fiber digestion and milk fat synthesis.
Milk fat improvement: Supplementing dairy cow diets with NaHCO₃ (typically 0.5–1.5% of dry matter) consistently improves milk fat percentage
Poultry heat stress management: Sodium bicarbonate supplementation helps maintain blood pH and electrolyte balance in broilers and layers during heat stress, improving performance and egg quality
Sodium source: Provides dietary sodium without the chloride load of sodium chloride (salt)
4. Pharmaceutical Industry — Antacid & Excipient
Antacid: Sodium bicarbonate is one of the oldest and most effective antacids, rapidly neutralizing stomach acid (HCl): NaHCO₃ + HCl → NaCl + H₂O + CO₂. Used in OTC antacid tablets, powders, and effervescent formulations.
Urinary alkalizer: Used to alkalinize urine in the treatment of urinary tract infections and to prevent uric acid kidney stones
IV sodium bicarbonate: Used in emergency medicine to treat metabolic acidosis and certain drug overdoses
Pharmaceutical excipient: Used as a buffering agent, effervescent agent, and tablet disintegrant in pharmaceutical formulations
Hemodialysis: Used as a bicarbonate buffer in dialysate solutions for kidney dialysis
5. Fire Suppression — Dry Chemical Extinguisher
Sodium bicarbonate is the active agent in BC-type dry chemical fire extinguishers, effective against Class B (flammable liquids) and Class C (electrical) fires. When discharged, the powder decomposes in the heat of the fire, releasing CO₂ and water vapor that smother the flame and interrupt the combustion chain reaction. It is also used in kitchen hood fire suppression systems for commercial cooking equipment.
6. Water Treatment
pH adjustment: Used to raise pH in acidic water treatment systems and swimming pools
Alkalinity increase: Raises total alkalinity in swimming pools and aquaculture ponds, stabilizing pH and improving water quality
Boiler water treatment: Used as a mild alkalizing agent in low-pressure boiler water
7. Personal Care & Cleaning
Toothpaste: Used as a mild abrasive and whitening agent in toothpaste formulations
Deodorant: Used as an odor neutralizer in natural deodorant products
Household cleaning: Used as a mild abrasive cleaner and deodorizer for kitchen and bathroom surfaces
Laundry: Used as a laundry booster to soften water and improve detergent performance
Packaging & Storage
Standard Packaging: 25 kg PP woven bags with inner PE liner
Other Options: 50 kg bags, 1,000 kg jumbo bags (FIBC), bulk shipment
Storage: Store in a cool, dry, well-ventilated warehouse. Keep away from moisture, acids, and high temperatures. Sodium bicarbonate slowly decomposes above 50°C — avoid storage near heat sources. Keep containers tightly sealed to prevent moisture absorption and CO₂ loss.
Safety: Sodium bicarbonate is non-toxic and generally recognized as safe (GRAS). It is mildly irritating to eyes and respiratory tract in dust form. Handle with standard PPE (gloves, goggles) when handling large quantities. Full MSDS/SDS available upon request.
Shelf Life: 2 years under proper sealed storage conditions
