Select the correct option if it is known that Ksp (AgCl) > Ksp (AgBr) > Ksp (AgI) — Electrochemistry Chemistry Question

💡 Solution & Explanation

The standard potential of a metal-insoluble salt electrode is related to its solubility product by: E°_X-\|AgX\|Ag = E°_Ag+\|Ag + 0.0591 * log(Ksp). Since Ksp values follow the order AgCl > AgBr > AgI, their standard reduction potentials follow the exact same trend: E°_Cl-\|AgCl\|Ag > E°_Br-\|AgBr\|Ag > E°_I-\|AgI\|Ag. Therefore, correct answer is B.
