Description of key information
Mn(2Na)IDHA_OECD 105: 491.27 g/L (unbuffered solution at 20 °C)
Key value for chemical safety assessment
- Water solubility:
- 491.27 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the manganese chelate Mn(2Na)IDHA was determined according to OECD Guideline 105 (Klimas, 2014). By applying the flask method, the test item was dissolved in buffered (pH 4, 7 and 10) and unbuffered solutions. The determination of the test substance was performed by spectrophotometric analysis.
The solubility of Mn(2Na)IDHA chelate in water with pH effect in temperature 20 ± 0.5°C is:
- in HPLC grade water: 491.27 g/dm3;
- in aqueous solution with pH4 effect: 502.56 g/dm³;
- in aqueous solution with pH7 effect: 397.95 g/dm³;
- in aqueous solution with pH10 effect: 340.99 g/dm³.
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.
