Key value for chemical safety assessment

Additional information

The vapour pressure of Nickel hydrogencitrate was measured according to OECD 104 (effusion method following Knudsen) under GLP-conditions. The stated values are 0.000129 and 0.000155 Pa at 20 and 25 °C, respectively.


Nickel hydrogencitrate and Trinickel dicitrate are comparable: Since citric acid is a multifunctional acid, at different pH values various intermediate ions like citrate, hydrogencitrate and dihydrogencitrate are formed.
