- Provide as many error sources in your calibration of the ion-selective electrode (ISE) as you can.Briefly explain the principle and application of potentiometry or pH meter or lon selective electrode.14-6. A cell was prepared by dipping a Cu wire and a saturated calomel electrode into 0.10 M CUSO4 solution. The Cu wire was attached to the positive terminal of a potentiometer and the calomel electrode was attached to the negative terminal. (a) Write a half-reaction for the Cu electrode. (b) Write the Nernst equation for the Cu electrode. (c) Calculate the cell voltage.
- An ion-selective electrode (ISE) produces voltage output (mV) proportional to solution pH. You have three standard pH solutions (4, 7, and 10). Assuming that pH 7 buffer solution is used together with pH 4 for calibration prior to measuring acidic solutions and together with pH 10 before measuring alkaline solutions, produce a flowchart of the calibration routine for a single pH ISE.When the difference in pH across the membrane of a glass electrode at 25C is 4.63 pH units, how much voltage is generated by the pH gradient? Assume that the constant in Equation 15-6 is 1.00.Please show a clear picture of the spreadsheet /excel file of the data including the equations used in excel.
