Consider the following half-reactions. Ag⁺(aq) + e^- → Ag(s)
E° = +0.80 V
Cu²⁺(aq) + 2 e^- → Cu(s)
E° = +0.34 V
Pb²⁺(aq) + 2 e^- → Pb(s)
E° = -0.13 V
Fe²⁺(aq) + 2 e^- → Fe(s)
E° = -0.44 V
Al³⁺(aq) + 3 e^- → Al(s)
E° = -1.66 V
Which of the following species will oxidize lead,Pb(s) ?

Question

Quizplus · Accepted Answer

Species with a higher reduction potential (E°) can oxidize species with a lower reduction potential. Ag^+ (E° = +0.80 V) and Cu^2+ (E° = +0.34 V) have higher reduction potentials than Pb^2+ (E° = -0.13 V), meaning they can accept electrons from Pb(s), oxidizing it.

Consider the Following Half-Reactions. Ag+(aq)+ E- → Ag(s)

Consider the Following Half-Reactions. Ag⁺(aq)+ E^- → Ag(s)
