Disodium carbonate CAS 497-19-8
Monohydrate 124.00 CAS 5968-11-6It is anhydrous or contains one molecule of water of hydration. It contains not less than 99.5 percent and not more than 100.5 percent of Na2CO3, calculated on the anhydrous basis.
Identification: It responds to the tests for Sodium 191 and for Carbonate.
Water: Dry about 2 g, accurately weighed, at 105 for 4 hours: the anhydrous form loses not more than 0.5%, and the hydrous form between 12.0% and 15.0%, of its weight.
Heavy metals: the limit is 0.001%.

CAS: decahydrate CAS 6132-02-1DESCRIPTION
It occurs as colorless crystals or as a white, granular or crystalline powder. It is anhydrous or may contain 1 or 10 molecules of water of hydration. It is freely soluble in water and insoluble in ethanol. Its solutions are alkaline to litmus. The anhydrous salt is hygroscopic, and the two hydrates are efflorescent. The decahydrate melts at about 32C.
Function: pH control.REQUIREMENTS
Identification: A sample gives positive tests for Sodium and for Carbonate.
Assay: Not less than 99.5% and not more than 100.5% of Na2CO3 after drying.
Lead: Not more than 4 mg/kg.
Loss on Drying Anhydrous: Not more than 1%; Monohydrate: Between 12.0% and 15.0%; Decahydrate: Between 55.0% and 65.0%.
