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 Ammonium hydroxide, and where each one comes from
9 measured values for 7 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.
- 36 °C @760 [mm Hg]
- PAC Chemical Database, U.S. Department of Energy
Melting point
1 record
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Vapour pressure
2 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 2160 mm Hg @ 25 °C
- Hazardous Substances Data Bank (HSDB)
- 2160 [mm Hg] @25 °C
- PAC Chemical Database, U.S. Department of Energy
Density
2 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- About 0.90 @ 25 °C/25 °C
- Hazardous Substances Data Bank (HSDB)
Solubility
1 record
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Exists only in solution
- Hazardous Substances Data Bank (HSDB)
pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- pH= 11.6 (1.0 N solution); 11.1 (0.1 N solution); 10.6 (0.01 N solution)
- 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.
- Intense, pungent, suffocating odor
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Ammonium hydroxide, 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.
