Describe how a fluoride selective ion electrode measures the fluoride ion concentration and explain why the potential approaches 0 at high concentrations

Expert Solution

Potential may approches to zero because...when the electrodes are immersed in pure water which will have high concentration any other solutions which does not contain the target ion then there will be no potential generated...

It all depends on the difference between the ISE diff voltage and the sum of the other voltages in the circuit..

ION-SELECTIVE ELECTRODE POTENTIOMETRY The fluoride ion concentration in a mouthwash sample was determined using ISE. Potentials of standard solutions containing fluoride ion are given in Table 1. The sample for ISE was prepared by pipetting 10.00 mL of the original mouthwash and diluting to 250.00 mL. The potential of the sample was recorded as –0.015 V. Table 1. Measurement of ISE potential of standard solutions containing fluoride ion. [F-], M Potential, mV 5.0 x 10-6 0.077 5.0 x 10-5 0.020...

A solid-state fluoride ion-selective electrode responds to F-but not to HF. It also responds to hydroxide ion at high concentration when

A solid-state fluoride ion-selective electrode responds to F-but not to HF. It also responds to hydroxide ion at high concentration when. Suppose that such an electrode gave a potential of +100 mV (versus S.C.E.) in 10-5 M NaF and +41 mV in 10-4 M NaF. Sketch qualitatively how the potential would vary if the electrode were immersed in 10-5 M NaF and the pH ranged from 1 to 13.

Explain the working principle of an ion-selective electrode.

Lab Experiment: Fluoride Speciation and Analysis by Flow Injection using Ion-Selective Electrode. Q1) what is the Nernst equation for the Fluoride Ion Selective Electrode (ISE)? How does this show that measured potential is proportional to Fluoride ion concentration? 2Q) What is a common cause of error when using a reference electrode? 3Q) IS the pH of solutions important when using the Fluoride ISE? If so, why?
