Question

For indicator electrodes, which statements are true? Indicator electrodes are made from relatively inert metals. Indicator electrodes work best when the electrode surface is large and clean. Platinum is a common indicator electrode. Platinum electrodes are more inert than gold electrodes. I, II, and IV II and III I, II, and IV I, II, and III I, II, III, and IV The potential of a silver electrode is measured relative to an Ag-AgCl, electrode for the titration of 100.0 mL of 0.100 M Cl- with 0.100 M Ag^+. What is the potential after 75.00 mL of titrant is added. E degree = 0.799 V for Ag^+, E = 0.197 V for the Ag-AgCl, electrode and Ksp = 1.8 times 10^10. 0.493 V 1.070 V 0.521 V 1.267 V 0.134 V
