Description of key information

Calcium difluoride is an inorganic salt. According to ECHA Guidance R7a, the dissolution of salts from their crystal lattice into individual ions in not intended to be covered by the endpoint dissociation constant.

Key value for chemical safety assessment

Additional information

A waiver is proposed for this data requirement. The substance is an inorganic salt and will dissociate into its constituent ions in aqueous solution (Ksp 3.95 x 10e-11 at 25 degrees Celsius).
