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 20mg/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 regression tools in Excel to calculate K and from the data in the table. The coefficient is close to 1 , and can be determined from a calibration curve. What value of K do you obtain from your plot? What value of do you obtain from your plot
