Problem 116IE
Fluoridation of drinking water is employed in many places to aid in the prevention of tooth decay. Typically the F- ion concentration is adjusted to about 1 ppb. Some water supplies are also “hard”; that is, they contain certain cations such as Ca2+ that interfere with the action of soap. Consider a case where the concentration of Ca2+ is 8 ppb. Could a precipitate of CaF2form under these conditions? (Make any necessary approximations.)
