Dissociation constant
Administrative data
- Endpoint:
- dissociation constant
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is hydrolytically unstable (half-life less than 12 hours)
- Justification for type of information:
- Sulphur trioxide reacts vigorously and extremely exothermically with water to give sulphuric acid. Therefore, it is not possible to experimentally determine the dissociation constant of this substance.
