Description of key information

The dissociation constant study does not need to be determined as this substance is hydrolytically unstable.

Key value for chemical safety assessment

Additional information

The substance is an inorganic salt which readily dissociates in water solution, providing Na+ as cation and SiF62- as anion. Then, the anion is undergoes hydrolysis to form Si(OH)4 and F-.
