Sodium Carbonate CAS 497-19-8
Sodium Carbonate (CAS 497-19-8), also called soda ash, is a white, odorless powder that absorbs moisture and dissolves into an alkaline solution. Glass plants use dense ash as a sodium source for flat glass, containers. Detergent plants use light soda ash as an alkaline builder. Chemical plants use it for sodium salts, alkalis, and water plants use it to raise pH, neutralize acid. It also serves paper, textile, food. UATChem supplies light and dense grades in 25 kg bags, ton bags, with COA, TDS and SDS on request.

What Sodium Carbonate Is
Sodium Carbonate is the disodium salt of carbonic acid, formula Na2CO3, CAS 497-19-8, sold as white powder, granules called soda ash. The powder absorbs moisture and dissolves into an alkaline solution, made as porous light ash or denser granules. Glass works use dense ash as sodium source, light ash serves detergents, chemicals. It adjusts pH in water and serves paper, textile, food. UATChem supplies it, with assay and particle data on COA, TDS.
Glass, Detergent, Chemical and Water Uses
- Glass. Dense soda ash is the sodium source for flat glass and glass containers.
- Detergent and soap. Light soda ash is an alkaline builder, paired with 4A zeolite powder.
- Chemical. It makes sodium salts, alkalis and sodium bicarbonate.
- Water, paper, textile and food. It adjusts pH, serves paper and textile work and foods under E500i.

FAQ
Q: What is sodium carbonate used for?
A: Soda ash feeds glass, builds detergents, makes sodium salts, adjusts pH and serves paper, textile and food.
Q: What is the difference between light and dense soda ash?
A: Light soda ash is a porous powder for detergents and chemicals, and dense ash is coarser granules for glass, with data on COA.
Q: How is sodium carbonate packed?
A: UATChem supplies soda ash in 25 kg woven bags and FIBC ton bags, sealed, dry and away from moisture, with COA, TDS and SDS.
Q: Is sodium carbonate used in water treatment?
A: Yes, the alkaline salt raises pH and neutralizes acidic water, supporting softening, with assay and lot data on COA and TDS.
