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 Sulfuric acid, and where each one comes from
24 measured values for 9 properties, read from 4 public databases. On 5 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point
4 records, 290 to 337 °C
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
- 554 °F
- NIOSH Pocket Guide
- 337 °C @760 [mm Hg]
- PAC Chemical Database, U.S. Department of Energy
Melting point
4 records, 10 to 11 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- 51 °F
- NIOSH Pocket Guide
Vapour pressure
4 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- Vapor pressure: 1 mm Hg at 145.8 °C
- Hazardous Substances Data Bank (HSDB)
- 5.93X10-5 mm Hg at 25 °C /from experimentally-derived coefficients/
- Hazardous Substances Data Bank (HSDB)
- 0.001 mmHg
- NIOSH Pocket Guide
- 0.001 mmHg
- OSHA Occupational Chemical Database
Vapour density
2 records differ
Above 1 the vapour sinks and collects in pits, sumps and low enclosed spaces.
- 3.4 (Air = 1)
- Hazardous Substances Data Bank (HSDB)
Density
5 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 1.8302 g/cu cm
- Hazardous Substances Data Bank (HSDB)
- Brown, viscous liquid; density: 1.675-1.710 at 15 °C /Commercial acid/
- Hazardous Substances Data Bank (HSDB)
- 1.84 (96-98% acid)
- NIOSH Pocket Guide
- 1.84 (96-98% acid)
- OSHA Occupational Chemical Database
- 1.8302 @25 °C
- PAC Chemical Database, U.S. Department of Energy
Solubility
2 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Miscible with water and alcohol with the generation of much heat and with contraction in volume
- Hazardous Substances Data Bank (HSDB)
- Miscible
- NIOSH Pocket Guide
Viscosity
1 record
Governs how far a spill spreads and how fast it soaks into a surface or a sorbent.
- 21 mPa.s at 25 °C
- Hazardous Substances Data Bank (HSDB)
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- 1 N solution = 0.3; 0.1 N solution = 1.2; 0.01 N solution = 2.1
- 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.
These are the public records read for Sulfuric 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.
