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.

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 Boric acid, and where each one comes from
15 measured values for 9 properties, read from 3 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.
Boiling point
1 record
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
Melting point
3 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Vapour pressure
1 record
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 1.6X10-6 mm Hg at 25 °C (2.136X10-4 Pa); log P (in Pa) = 26.83 - 9094/T where T is deg K
- Hazardous Substances Data Bank (HSDB)
Density
3 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 1.5 g/cu cm
- Hazardous Substances Data Bank (HSDB)
- 1.435 @25 °C
- PAC Chemical Database, U.S. Department of Energy
Solubility
3 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Slightly unctuous to touch; volatile with steam; solubility in water increased by hydrochloric, citric or tartaric acids
- Hazardous Substances Data Bank (HSDB)
- Solubility in water is increased by hydrochloric acid
- Hazardous Substances Data Bank (HSDB)
- In water, 5.0X10+4 mg/L at 25 °C
- Hazardous Substances Data Bank (HSDB)
Partition coefficient (log Kow)
1 record
Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.
- log Kow = 0.175
- Hazardous Substances Data Bank (HSDB)
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- pH = 5.1 (0.1 Molar)
- 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.
- Boric acid decomposes in heat above 100 °C forming boric anhydride and water
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Boric acid, 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.
