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 bicarbonate, and where each one comes from
9 measured values for 6 properties, read from 2 public databases. On 1 property the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
1 record
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- Approximately 50 °C
- Hazardous Substances Data Bank (HSDB)
Density
2 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 2.20 g/cu cm
- Hazardous Substances Data Bank (HSDB)
Solubility
3 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- In water, 10.3 g/100 g water at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Soluble in 10 parts water at 25 °C; 12 parts water at about 18 °C
- Hazardous Substances Data Bank (HSDB)
- Insoluble in ethanol
- Hazardous Substances Data Bank (HSDB)
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- Freshly prepared 0.1 molar solution at 25 °C: 8.3
- 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
1 record
The temperature at which the substance breaks down, often into products more hazardous than itself.
- Sodium bicarbonate starts decomposing when heated over 50 °C, releasing CO2, H2O and Na2CO3, with total decomposition at 270 °C
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Sodium bicarbonate, 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.
