Fluoride and hydrogen fluoride gas are harmful, irritating and corrosive substances. (i) If the suspected fluoride is soluble add dilute nitric acid and silver nitrate solution. (ii) You can warm a solid fluoride with conc. sulphuric acid and hold in the fumes (ONLY!) a glass rod with a drop of water on the end. pH: between 2.8 and 3.5, in a freshly prepared 0.4% solution. Loss on drying: Dry it at 105C for 4 hours: it loses not more than 0.5% of its weight. Water-insoluble substances: Transfer about 10 g, accurately weighed, to a 400-mL plastic beaker, add 200 mL of water, and stir with a plastic rod for 3 minutes, or until no more solid dissolves.

Fluoride has a primary standard of 4 mg/l and a secondary standard of 2 mg/l. It is an essential constituent for maintaining good health. Fluoride concentrations between 0.6 and 1.7 mg/l in drinking water have a beneficial effect on the structure and resistance to decay of children’s teeth, but excess levels may cause mottling of teeth.
