Henry's Law constant
Administrative data
- Endpoint:
- Henry's law constant
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The reliability of the QSAR result can not be quantified. It is beliewed that the result gives correct basic indication of the volatilization and distribution of the substance in water-air systems.
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6
Data source
Materials and methods
Test material
- Reference substance name:
- Tetrahydroxysilane
- EC Number:
- 233-477-0
- EC Name:
- Tetrahydroxysilane
- Cas Number:
- 10193-36-9
- IUPAC Name:

Constituent 1
Results and discussion
Henry's Law constant H
- H:
- < 0 atm m³/mol
Any other information on results incl. tables
Dissolved silica (and silicon) as orthosilicic acid is poorly volatile substance and it partitions pre-dominantly in the aquatic phase. Calculated estimate of volatilisation behaviour of silicic acid from water to air gives Henry’s law constant value 6*10 -16atm*m3/mol indicating no volatilisation.
