Description of key information

Weight of evidence approach based on peer-reviewed handbook values (> 0.5 kg/L, three values). 

Key value for chemical safety assessment

Water solubility:
500 000 mg/L
at the temperature of:
20 °C

Additional information

Temperature of measurement was not reported. It is anticipated that the values refer to ambient temperature. Based on the high water solubility it can safely be concluded that the water solubility of Nitric acid is >0.5 kg/L (miscible) at a temperature of 20 deg C.
