MSDS Sodium Bicarbonate (NaHCO3) – Safety Data Sheet & GHS Hazards

Summary MSDS for Sodium Bicarbonate (NaHCO3), CAS 144-55-8: substance identity, GHS hazard classification, hazard and precautionary statements, and links to the manufacturer's official SDS.

Identity summary

Name	Sodium Bicarbonate
Other names (IUPAC)	sodium hydrogen carbonate
Molecular formula	NaHCO3
CAS number	144-55-8
Molar mass	84.007 g/mol
PubChem CID	516892

Molar mass of NaHCO3 and how to calculate it

The molar mass of NaHCO3 is 84.01 g/mol, the sum of the relative atomic masses of all atoms in the formula: 22.990 + 1.008 + 12.011 + 3 × 15.999 = 84.01 g/mol.

Element	Atoms	Atomic mass	Contribution	Mass %
Na	1	22.990	22.99	27.37%
H	1	1.008	1.01	1.20%
C	1	12.011	12.01	14.30%
O	3	15.999	48.00	57.14%

So 1 mol of NaHCO3 weighs 84.01 g, and 1 L of a 0.1 M solution needs 8.401 g of pure NaHCO3. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.

What is an MSDS/SDS?

An MSDS (Material Safety Data Sheet), now called an SDS (Safety Data Sheet), is a 16-section document describing the hazards, handling, storage, first aid, and disposal of a chemical. Read the full MSDS guide and other MSDS pages.
