Question
![Fluoride ion selective electrodes obey the following equation:
E(V)-K-B(0.0592)log[F]
where the fluoride concentration is expressed as mol/L and the temperature coefficient p 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 3. Use the plotting and linear regression tools in Excel to
calculate K and 3 from the data in the table. The coefficient is close to 1, and can be determined from a calibration curve.
