The price of stannous fluoride varies from $22 to $40/lb where as NaF dental grade has 45% available fluoride ion and a price is less than $3/lb. Currently, stannous fluoride is used in special formulations and gels which are recommended by dentists or used in their offices.
Stannous Fluoride Molecular formula F 2 Sn Molecular weight 156.71 Percent composition F 24.25%, Sn 75.75%
This represents the formula SnF 2, which is more properly named tin(II) fluoride. The other fluoride of tin is SnF 4 , which was previously called stannic fluoride but is now named tin(IV) fluoride. Example \(\PageIndex{6}\): Naming Ionic Compounds
Results. XANES spectra showed a diverse distribution of tin species and varying degrees of SnF 2 oxidation. In vitro antimicrobial assessment indicated significant differences in performance, which may be correlated to the differences in tin speciation and oxidation state. Conclusions.
