u = (2)²) id (spheri Date чис Subject Month Year. 58 3.9 Discuss the mechanism by which the potential of a platinum electrode becomes poised by immer- sion into a solution of Fe(II) and Fe(III) in 1 M HCl. Approximately how much charge is required to shift the electrode potential by 100 mV? Why does the potential become uncertain at low concentra- tions of Fe(II) and Fe(III), even if the ratio of their concentrations is held near unity? Does this ex- perimental fact reflect thermodynamic considerations? How well do your answers to these issues apply to the establishment of potential at an ion-selective electrode? فصل دوم مراجع استاد
*23-26 A 0.400-g sample of toothpaste was boiled with a 50-mL solution containing a citrate buffer and NaCl to extract the fluoride ion. After cooling, the solution was diluted to exactly 100 mL. The potential of an ion-selective electrode with a Ag-AgCl(sat'd) reference electrode in a 25.0-mL aliquot of the sample was found to be -0.1823 V. Addition of 5.0 mL of a solution containing 0.00107 mg F"/mL caused the potential to change to -0.2446 V. Calculate the mass percent- age of F in the sample.
An analyst wants to find out the active surface of his electrode before conducting his analyzes. To do this, he carried out a series of measurements by cyclic voltammetry (CV) using a 1 mM solution of K4Fe(CN)6 dissolved in 0.1M NaCl.
