Description of key information
Silver nitrate is an inorganic substance that forms an ion crystal lattice, which contains silver cations and nitrate anions, with a melting point of 212°C. It is scientifically not plausible that silver nitrate could exist in molecular form in the gas phase due to its ionic character. Thus, the concept of vapour pressure, i.e. the saturation pressure above a solid or liquid does not apply. Furthermore, silver nitrate decomposes in the temperature range 250-440°C. Silver nitrate is readily soluble in water, in which it dissolves into ions, which cannot evaporate. In consequence, the testing for vapour pressure is waived for silver nitrate, since such testing would not provide any meaningful information on the substance, nor information applicable to the assessment of environmental fate or for any further animal or environmental studies.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
This is an inorganic non volatile substance. A very low value has been included for the exposure assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
