Description of key information
Weight of evidence approach based on peer-reviewed handbook values (highly soluble, 5480 g/L; miscible). Taking its hygroscopic properties into consideration, it is concluded that phosphoric acid is miscible with water.
Key value for chemical safety assessment
- Water solubility:
- 1 000 g/L
- at the temperature of:
- 20 °C
Additional information
Phosphoric acid is miscible with water; therefore it was concluded that the water solubility is greater than 1000 g/L at 20°C.
Value used for CSA: 1000 g/L at 20°C.
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.
