Sodium Carbonate (CAS 497-19-8) possesses a molecular formula of Na2CO3 and a molecular weight of 105.988 g/mol. In its anhydrous form, it appears as odorless, small crystals or a crystalline powder. It is stable at ordinary temperatures, becoming anhydrous at 100 °C and exhibiting high solubility in water, necessitating careful handling in formulations where precipitation may occur. Buyers should specify the minimum purity expected in orders, typically around 99%, and be aware of its physical form as either powder or crystallized form when assessing compatibility for specific applications.

Frequently asked questions
What is the CAS number of Sodium Carbonate?
The CAS registry number for Sodium Carbonate is 497-19-8. Its chemical formula is Na2CO3, with a molecular weight of 105.988 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.
What are the other names for Sodium Carbonate?
Sodium Carbonate is also referred to as Sodium Carbonate, Soda Ash, Disodium carbonate, Carbonic acid disodium salt, Sodium carbonate anhydrous and Calcined soda. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of Sodium Carbonate is supplied?
Sodium Carbonate is supplied as Technical grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is Sodium Carbonate supplied at?
Sodium Carbonate is supplied at a concentration of 99%. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What is the purity of Sodium Carbonate?
The purity/assay figure recorded for Sodium Carbonate is 99. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.
What does Sodium Carbonate look like?
Sodium Carbonate is described as odorless crystalline powder. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is Sodium Carbonate used for?
Common applications include water treatment — Alkalinity correction of water sources, glass manufacturing — Source of sodium for glass formulations, agricultural applications — Soil amendment to alter pH, detergents & soaps — Active ingredient in cleaning products and laboratory reagents — pH buffering and titration agent. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
Which industries use Sodium Carbonate?
Sodium Carbonate is supplied to the Water Treatment, Food Processing & Beverage, Agriculture & Agrochemicals, Cleaning & Detergents and Laboratories & Research sectors. These are the industries this product is listed against in our catalogue; if your application falls outside them, we can advise on suitability before you order.
What packaging is Sodium Carbonate available in?
Available in 25Kg bags from TATA CHEMICALS EUROPE. Where a different pack size or bulk delivery is required, it is confirmed at quotation stage against availability rather than listed here as standard.
