WebThere are tests to identify Fluoride (F -) anion in qualitative analysis. Fluoride ion forms aqueous solutions with some metal cations and sometimes forms precipitates with some cations. Fluorine and fluoride differs from other halogens and halides respectively. Hydrogen fluoride (HF) is a weak acid. Other hydrogen halides such as HCl, HBr, and ... Webtusk. Fluorine and phosphate analyses of these samples give the ratio of fluorine and phosphate (100 F/P205) ranging between 2.32 to 5.98 (Table. 1). Kshirsagar (1993) has proposed a chart correlating the fluorine values in fossil bones with dates obtained by other dating methods (Table. 2). Using this chart for comparison, it becomes clear
