Description of key information

Weight of evidence approach based on three peer-reviewed values from handbooks (1.5129 at 20°C (two values) and 1.5128 at 20°C) are used to conclude on the relative density of Nitric acid.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The three available values at 20°C are in a very close range. The final value is calculated as the mean from the 3 available values at 20°C.

Supporting data provide densities of 1.550 g/cm3 and 1.502 g/cm3at unspecified temperatures.
