Reference
Endpoint:
vapour pressure
Type of information:
other: statement
Adequacy of study:
key study
Study period:
22 April 2010-17 May 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Based on the molecular structure and composition of the test substance a statement rather than a full study was considered sufficient to cover this endpoint. The statement was written by an expert and under GLP.
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.4 (Vapour Pressure)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
other: Expert statement
Key result
Temp.:
20 °C
Vapour pressure:
< 0 Pa
Remarks on result:
not determinable because of methodological limitations
Remarks:
Estimated value

Magnesium nitrate consists of magnesium and nitrate ions which are both non-volatile. Magnesium nitrate is therefore also not volatile (vapour pressure at 20˚C of <1E-05 Pa). Calculation of the vapour pressure from the structure is not possible.

Conclusions:
Magnesium nitrate consists of the non-volatile magnesium and nitrate ions and is therefore not volatile. The vapour pressure of magnesium nitrate is estimated to be < 1E-5 Pa at 20°C.

Description of key information

The inorganic solid substance consists of non volatile magnesium and nitrate ions. The volatilty of this substance is estimated to be < 1  E-5 Pa at 20°C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

Calculation of the vapour pressure is not possible for an inorganic substance (not within the applicability domain of the databases).
