Studies on the Toxicity and Decomposition of Fluosilicic Acid
This paper discusses a study of the toxicity of fluosilicic acid and fluosilicates that was initiated to determine the concentration of fluosilicic acid and its salts required to kill fish. Fluosilicic acid and silicon tetrafluoride decompose rapidly above pH 3.6, although the rate of decomposition is retarded by the presence of extra fluoride ions. Either the rate of decomposition or the manner of decomposition can favor a supersaturated solution of calcium fluoride at pH 6.5 for a period of several hours at a 0.002M concentration. At any given pH, the toxicities of fluoride and fluosilicate ion are equivalent.
