Fluoride, in the form of sodium silicofluoride (Na2SiF6), is commonly added to municipal drinking water to prevent tooth decay. It is generally added at a level of 1.0 mg/L, but its maximum concentration level (MCL) cannot exceed 4.0 mg/L. You have been assigned to prepare a liter of a standard solution that contains 1.000 mg/L fluoride. Explain, in detail, how you would prepare this solution so a labmate could prepare it from your instructions. Your answer must include a brief...

It is recommended the drinking water contain 1.6 ppm fluoride (F-) to prevent tooth decay. Consider a cylindrical reservoir with a diameter of 5.00 x 102 m and a depth of 20.0 m (the volume of a cylinder = r2h). How many grams of fluoride should be added to give 1.6 ppm? Fluoride is provided by dissolving H2SiF6. How many grams of H2SiF6 contain this amount of fluoride?
