Description of key information
The density at 25°C was determined as 1.58 g/cm³.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.58
Additional information
The density of Manganese (II) acetate tetrahydrate was reliably determined to be 1.58 g/cm³ in a study equivalent to OECD guideline 109. Although the anhydrous form is the substance to be registered according to the requirements under REACH, this form practically never occurs and hence it is scientifically justified to perform the test on the most prevalent tetrahydrat. This is supported by the data taken from a peer-revied database which states the density to be 1.59 g/cm³. These values are nearly identical and can be explained due to differences in the determination method and the temperature, which are not stated in the database GESTIS.
Two independently acting literature sources (one peer-reviewed handbook, one internet source) stated the relative density of anhydrous Manganese acetate to be 1.74 g/cm³. Although the magnitude of the value is plausible and the sources are reliable and values from the two different sources are identic, the relative density of 1.74 cm³ can be considered as potentially relevant for the anhydrate. Another peer-reviewed source, however, stated the density of the anhydrate to be 1.6 g/cm³. This value should be taken also into account, especially because the density of the anhydrate is not expected to differ that much from the values of the tetrahydrate.
In summary, the density of the tetrahydrate of 1.58 g/cm³ is considered to be the more relevant as well as reliable one as this is the most prevalent form of Manganese (II) acetate and ste study was classified as Klimisch 2.
