Description of key information

Published handbook data report the relative density at 17.5 ⁰C  to range from 1.0407 -1.2742 g/cm3 for solutions of 5 -30%

Key value for chemical safety assessment

Additional information

The relative density at 17.5 ⁰C is reported to be (Merck Index, 2001):

1.0407 g/cm3for a 5% solution

1.0834 g/cm3 for a 10% solution

1.1281 g/cm3 for a 15% solution 1.174 g/cm3 for a 20% solution 1.2235 g/cm3 for a 25% solution 1.2742 g/cm3 for a 30% solution.

The density of a 60.97% aqueous solution of hexafluorosilicic acid is reported to be 1.4634 at 25 degrees Celsius (Hollemann et al, 1995).
