A value with no row here was assembled from more than one record, so no single record is credited for it. The draft you buy carries this table as an appendix covering all 16 sections.

- PubChem — GHS classification
- PubChem — compound record
- PubChem — names and identifiers

Sections 1.3 and 1.4 are withheld here because the supplier and emergency contact blocks carry your own company details in the draft you buy. Every draft needs review by a competent person before it is issued.
Measured values for Sodium carbonate, and where each one comes from
15 measured values for 6 properties, read from 2 public databases. On 2 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point
1 record
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
- Decomposes on heating by CO2 loss
- Hazardous Substances Data Bank (HSDB)
Melting point
2 records, 851 to 856 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Density
4 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 2.54 g/cu cm
- Hazardous Substances Data Bank (HSDB)
- Hexagonal crystals; density: 4.7 g/cu cm; Mohs hardness 4 /Trona/
- Hazardous Substances Data Bank (HSDB)
- Bulk density: 0.59-1.04 g/mL
- Hazardous Substances Data Bank (HSDB)
Solubility
5 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- In water, 30.7 g/100 g water at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Solubility in water at 0, 10, 20 and 30 °C is 6, 8.5, 17 and 28 wt %, respectively
- Hazardous Substances Data Bank (HSDB)
- Soluble in water
- Hazardous Substances Data Bank (HSDB)
- Sparingly soluble in ethanol; insoluble in acetone
- Hazardous Substances Data Bank (HSDB)

Odour
1 record
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
Decomposition temperature
2 records, each a different case
The temperature at which the substance breaks down, often into products more hazardous than itself.
- Begins to decompose at 400 degrees C to evolve carbon dioxide gas
- Hazardous Substances Data Bank (HSDB)
- When heated to decomposition it emits toxic fumes of Na2O
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Sodium carbonate, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
