Chapter 4, Problem 4.171(choose chapter or problem)
Public water supplies are often fluoridated by the addition of compounds such as NaF, H2SiF6, and Na2SiF6. It is well established that fluoride helps prevent tooth decay; however, care must be taken not to exceed safe levels of fluoride, which can stain or etch tooth enamel (dental fluorosis). A safe and effective concentration of fluoride in drinking water is generally considered to be around 1 mg/L. How much fluoride would a person consume by drinking fluoridated water in 1 year? What would be the equivalent mass as sodium fluoride?
