Fluoride ion is poisonous in relatively low amounts: 0.2 g of F− per 70 kg of body weight can cause death. Nevertheless, in order to prevent tooth decay, F− ions are added to drinking water at a concentration of 1.00 mg of F− ion per L of water.
How many liters of fluoridated drinking water would a 70−kg person have to consume in one day to reach this toxic level?
