Request SDS →Sodium carbonate monohydrate (CAS 5968-11-6), Na2CO3 H2O, is a hydrated form of soda ash. It is used to manufacture glass, sodium salts, and soap; in textile washing, scouring, and bleaching and in water softening; and in photography and analytical chemistry as an alkalizer and acid-base standard.
Frequently Asked Questions
What is sodium carbonate monohydrate used for?
Sodium carbonate monohydrate (CAS 5968-11-6, Na2CO3.H2O), a hydrated form of soda ash, is used to manufacture glass, sodium salts, and soap; in textile washing, scouring, and bleaching and in water softening; and as an alkalizing agent and acid-base standard in photography and analytical chemistry.
Is sodium carbonate the same as sodium carbonate monohydrate?
They are closely related. Sodium carbonate monohydrate (Na2CO3.H2O, CAS 5968-11-6) is the hydrated form, carrying one water molecule per formula unit, while anhydrous soda ash is Na2CO3. They differ in CAS number and molecular weight; specify the form required when ordering.
What is another name for sodium carbonate monohydrate?
It is a hydrated form of soda ash and is sometimes referred to by trade designations for monohydrate soda ash. The unambiguous identifiers are CAS 5968-11-6 and formula Na2CO3.H2O, which appear on our CoA.
Is sodium carbonate monohydrate the same as baking soda?
No. Baking soda is sodium bicarbonate (NaHCO3). Sodium carbonate monohydrate is Na2CO3.H2O (CAS 5968-11-6), a more strongly alkaline soda-ash form with a different CAS number and application set.
What is the CAS and HS code for sodium carbonate monohydrate?
It is CAS 5968-11-6, formula Na2CO3.H2O, classified under HS 2836.20 (disodium carbonate). These identifiers are documented on the CoA and customs paperwork. Request a bulk quote for packaging and lead time.
