Description of key information

Relative density of dipotassium disulfite: 2.3

Key value for chemical safety assessment

Additional information

For the evaluation of this endpoint data from the CRC handbook were used as key information. According to ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a, specific handbook data for physic-chemical properties are considered to be a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the CRC Handbook of Chemistry and Physics.

Two further secondary sources (Hawley's Condensed Chemical Dictionary and IARC Monographs on the Evaluation of Carcinogenic Risks to Humans) were used to support the key information. All references indicate that dipotassium disulfite has a (relative) density of 2.3.
