Description of key information
The density of potassium sulfite is 2.353 g/cm³ at 20 °C, the relative density 2.353 (based on the density of water at 3.98 °C).
Key value for chemical safety assessment
- Relative density at 20C:
- 2.353
Additional information
For determination of the density of Potassium sulfite, the pycnometer method with petroleum as displacement liquid was carried out in accordance with the OECD-Guideline for the testing of chemicals (1995), 109 "Density of Liquids and Solids": The density of Potassium sulfite was determined to be 2.353 g/cm³ at 20 °C.
The available value for Potassium sulfite is for the density. The key value should be entered as the relative (specific) density of the substance. Since no reference for this calculation is explicitly stated, it can be assumed that water at 4 °C (or, more precisely, 3.98 °C, which is the temperature at which water reaches its maximum density) is the reference. The density of water is (approximately) 1 g/cm3, which makes relative density calculations particularly convenient: the density of the object only needs to be divided by 1.
