Measured values for Nitric acid, and where each one comes from
23 measured values for 7 properties, read from 4 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
4 records agree
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
- 181 °F
- NIOSH Pocket Guide
- 83 °C @760 [mm Hg]
- PAC Chemical Database, U.S. Department of Energy
Melting point
4 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- -44 °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.
- 63.1 mm Hg at 25 °C
- Hazardous Substances Data Bank (HSDB)
- 48 mmHg
- NIOSH Pocket Guide
- 75 [mm Hg] @28.4 °C
- PAC Chemical Database, U.S. Department of Energy
Density
4 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 1.5129 g/cu cm at 20 °C
- Hazardous Substances Data Bank (HSDB)
- (77 °F): 1.50
- NIOSH Pocket Guide
- 1.5129 @ 20°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.
- Very soluble in water
- Hazardous Substances Data Bank (HSDB)
- Miscible with water
- 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.
- 1.092 mPa.s at 0 °C; 0.746 mPa.s at 25 °C; 0.617 mPa.s at 40 °C
- Hazardous Substances Data Bank (HSDB)
Odour
3 records, each a different case
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- Characteristic choking odor
- Hazardous Substances Data Bank (HSDB)
- Acrid; Sweet to acrid
- Hazardous Substances Data Bank (HSDB)
- Acrid, suffocating odor
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Nitric 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.
