Description:
Sodium Carbonate is a white, alkaline, water-soluble salt used in a wide range of industrial, chemical, and domestic applications. It is commonly known as soda ash (anhydrous form) or washing soda (hydrated form). As a strong alkaline base, it is widely used for pH adjustment, neutralization, and cleaning.

Applications:

Industrial & Chemical Manufacturing

• Key ingredient in glass production (reduces melting point of silica)

• Used in detergents and soaps as a water softener and alkaline builder

• Employed in paper, textile, and dyeing industries for pH regulation and chemical processing

• Serves as a fluxing agent in metallurgy and ceramics

Laboratory & Water Treatment

• Common pH buffer and titration reagent

• Used in alkaline cleaning solutions and acid neutralization

• Controls alkalinity in swimming pools and boiler water treatment

Pyrotechnics

• Occasionally used as a pH buffer, flame modifier, or alkaline filler in chemical formulations

• May act as a flame color suppressor or stabilizer in colored compositions

Household Use

• Multi-purpose cleaning agent and laundry booster

• Removes grease, oil, and stains from surfaces and fabrics

• Used to strip paint, clean drains, and soften water

Properties:

• pH (1% solution): ~11.5

• Solubility in Water: ~22 g/100 mL at 20 °C

• Melting Point: 851 °C

• Density: ~2.5 g/cm³ (anhydrous)

Handling & Safety:

• Irritating to eyes and skin — avoid direct contact

• Do not inhale dust — use in well-ventilated areas

• Store in sealed containers in a dry place to avoid clumping

• Not flammable or reactive under normal conditions

Packaging Options:
