The Potential of a Silver Electrode Is Measured Relative to an Ag-AgCl

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^o = 0.799 V for Ag⁺,E = 0.197 V for the Ag-AgCl electrode and K_sp = 1.8 × 10⁻¹⁰.

A) 0) 493 V
B) 1) 070 V
C) 0) 521 V
D) 1) 267 V
E) 0) 134 V
