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

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.
