State maximum concentration level

Reference no: EM13163353

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. Must include a brief explanation of the calculations you did to get the mass of substance that will be used to prepare the solution.
