(3) A student generated the following calibration curve by recording the potential readings when a fluoride ion selective electrode is dipped in a series of fluoride standards: y = 50.5 – 54.62log[F- ]. If a mouthwash solution gave a certain potential reading (e.g. 210 mV), what is the molar concentration of fluoride in the mouthwash solution?

    Fluoride ion selective electrodes obey the following equation:       E(V) = K - (0.0592)log[F-] where the fluoride concentration is expressed as mol/L and the temperature coefficient is normally equal to 1. In a normal calibration procedure you dilute a standard fluoride solution to between 10 and 20 mg/L fluoride ion and then measure the response of the electrode. You then plot the data and do a linear regression to obtain the fitting coefficients K and . Use the plotting and linear...
