What is Sodium Bicarbonate CAS 144-55-8?

Sodium Bicarbonate CAS 144-55-8 is sodium hydrogen carbonate, with the formula NaHCO3 or CHNaO3 and molecular weight 84.01 g/mol. It is commonly known as baking soda or bicarbonate of soda.

How does Sodium Bicarbonate work as a leavening agent?

It reacts with acidic ingredients or heat to release carbon dioxide gas, which creates rise and texture in baked goods and confectionery. The reaction is the same principle behind its use in effervescent products.

What is the difference between food, feed, and industrial grades?

The main differences are assay and allowable impurity levels. Food and feed grades are controlled for limits such as arsenic, heavy metals, chloride, and iron, while industrial grade is specified for technical applications where those limits may be broader.

What pH and buffering properties does Sodium Bicarbonate provide?

In water it forms a mildly alkaline solution, typically around pH 8.3, and can act as a pH regulator or buffer. This makes it useful in foods, beverages, personal care, cleaning products, and water or gas treatment.

What are common non-food uses of Sodium Bicarbonate?

Non-food uses include dry chemical fire suppression, feed buffering, flue-gas treatment, gentle cleaning, rubber or plastics foaming, and laboratory pH adjustment. It is widely used because it is low-cost, non-flammable, and comparatively mild.

Product Description

Sodium Bicarbonate, CAS 144-55-8, also called sodium hydrogen carbonate or baking soda, is a widely used inorganic bicarbonate.

Synonyms: Sodium hydrogen carbonate; Baking soda; Bicarbonate of soda; Sodium acid carbonate; Carbonic acid monosodium salt.

CAS: 144-55-8.

It has a molecular weight of 84.01 g/mol and appears as a free-flowing white crystalline powder.

It has a total alkali content of 99.0–100.5% and dissolves easily in water to form a mildly alkaline solution around pH 8.3.

It reacts with acids or heat to release carbon dioxide gas, which is the basis for leavening and fire suppression.

It is used in the food industry as a leavening agent, carbon dioxide generator and preservative.

It is added to animal feed as a buffer to neutralize rumen acidity and improve heat-stress resistance.

It is used in flue-gas desulfurization to remove sulfur dioxide from exhaust gases.

It is used as a filler and buffering agent in washing powders, and to neutralize tanning agents in leather processing.

It is used in dry chemical fire extinguishers and in bath bombs, toothpaste and mouthwash.

It is used in rubber and plastics foaming and in laboratory or water-treatment pH adjustment.

It is low-cost, non-flammable and comparatively mild, making it widely useful across industries.

Confirm appearance, total alkali content, loss on drying, pH, arsenic, heavy metals, ammonium salts, clarity, whiteness, chloride, iron and particle size.

Store in a cool, dry, well-ventilated warehouse, away from acids and, for food grade, away from toxic substances.

Keep bags tightly closed, as the powder is sensitive to moisture and can cake or clump in humid air.

Confirm packaging with the requested quantity and destination requirements.
