Measured values for Zinc chloride, 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.
- 1350 °F
- NIOSH Pocket Guide
- 732 °C @760 [mm Hg]

Melting point
4 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- Approximately 290 °C
- Hazardous Substances Data Bank (HSDB)

Vapour pressure
3 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.

pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- Aqueous solutions of zinc chloride are acidic (pH = 1.0 for 6 M)
- Hazardous Substances Data Bank (HSDB)
Odour
2 records, each a different case
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- FUME HAS AN ACRID ODOR /ZINC CHLORIDE FUMES/
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Zinc chloride, 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.
