Description of key information
Sulphuric acid is a strong mineral acid that dissociates readily in water to hydrogen ions and sulphate ions (at environmentally relevant pH) and is totally miscible with water. The hydrogen ions, although not degraded as such due to their elemental nature, contribute to the pH of the local environment and are potentially mobile. The sulphate ions are incorporated into the various mineral species present in the environment. No further information is necessary.

- Koc at 20 °C:

Additional information
Sulphuric acid is a strong mineral acid that dissociates readily in water to hydrogen ions and sulphate ions (at environmentally relevant pH) and is totally miscible with water.

The sulphate ions are incorporated into the various mineral species present in the environment. No further information is necessary.
For the purposes of the risk assessment the Koc has been set to 1 to represent the low propensity for binding to organic carbon.
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.
