| Abstract: | A method for the determination of hexafluorophosphate ion by amperometric titration has been studied.Tetraphenylarsonium ion is used as the indicating ion.The paper also reports the relevant polarographic data on the arsonium ion.The method was tested for the titration of lithium hexafluorophosphate solution. The results were compared with another analytical method called nitron precipitation and they accord with well each other.The titration was not interfered by fluoride. This method has the advantages of quickness and precision.; |
