Add silver nitrate solution. flouride is precipitated as silver fluoride
NaCl + CaF2 Check solubility rules to see if it even forms a precipate
No. Boiling water will not remove fluoride. Distilling it will.
Boiling water does not remove fluoride; in fact, it can concentrate the fluoride content. When water is boiled, some of the water evaporates, but the fluoride remains in the liquid. To remove fluoride, more advanced methods such as reverse osmosis, distillation, or activated alumina filtration are required.
To recover the precipitate.
Boiling water does not effectively remove fluoride. Fluoride is a stable compound that remains in water even after boiling, as it does not evaporate with the steam. To reduce fluoride levels in drinking water, other methods such as reverse osmosis or activated alumina filtration are recommended.
Calcium carbonate and calcium phosphate are common calcium salts that can precipitate in certain conditions. Calcium carbonate can precipitate in alkaline solutions, while calcium phosphate can precipitate in acidic solutions.
Fluoride is water soluble. It dissolves in water to form fluoride ions.
Boiling water does not remove fluoride. As water evaporates, the fluoride concentration actually increases slightly. Special filters like reverse osmosis systems are needed to effectively remove fluoride from water.

Yes, fluoride can evaporate from water when it is heated.
Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.
But merely boiling the water will not eliminate the fluoride and can in fact concentrate it because you have the same amount of fluoride in less water. You can distill the water. Meaning you can boil the water then capture the steam, which will be pure. But the process is expensive. You need special filters to remove the fluoride.
No, a water softener does not remove fluoride. It only removes hardness-causing minerals like calcium and magnesium. To remove fluoride, you need a different system, like reverse osmosis.
Distillation does remove at least some fluoride - this is why a dentist will recommend fluoride treatment at your 6-month dental cleaning if you drink distilled or filtered water. However, to get all the fluoride out the water would have to be deionized.
Fluoride is added to public drinking water to help prevent cavities.
