AS 3.6g soil sample was treated with HClO4 and HF was distilled from the mixture. The HF distillate was then diluted to a volume of 50.0 mL. Measurement with a fluoride ISE resulted in a potential of +95 mV. Exactly 5.00 mL of 1×10^-3 M F- standard was added to the 50.0mL solution and the potential on the fluoride ISE became +68mV. Calculate the fluoride content in the soil as %F-.
