What are the three common fluoride chemicals used in water treatment?

Fluorosilicic Acid, Sodium Fluoride, and Sodium Fluorosilicate are widely recognized as three common fluoride chemicals utilized in water treatment processes for the purpose of fluoridation.

These chemicals are chosen primarily for their effectiveness in preventing dental cavities among populations consuming treated water. Fluorosilicic acid, for instance, is a byproduct derived from the production of phosphate fertilizers and is commonly used due to its solubility in water, making it an effective choice for fluoridation. Sodium fluoride is another well-known fluoride compound that is effective in providing the necessary fluoride ions in drinking water. Finally, sodium fluorosilicate serves a similar purpose, acting as a source of fluoride in treated water.

The other options contain compounds that are either not primarily used for fluoride treatment or are not relevant to the context of fluoridation in drinking water. Therefore, the selection of the first set of chemicals aligns with standard practices in water treatment aimed at enhancing dental health through controlled fluoridation.
