Given: Zn²⁺(aq)+ 2e^- Zn(s); E° = -0.76 V Cu²⁺(aq)+ 2e^- Cu(s); E° = 0.34 V Cr₂O₇^2-(aq)+ 14H⁺(aq)+ 6e^- 2Cr³⁺(aq)+ 7H₂O(l); E° = 1.33 V Which of the following species is the strongest oxidizing agent?

Question

Quizplus · Accepted Answer

The strongest oxidizing agent is the species with the highest positive standard reduction potential (E°) value, as it has the greatest tendency to accept electrons and undergo reduction. Among the given species, Cr₂O₇^2- has the highest positive E° value of 1.33 V, indicating that it has the strongest oxidizing power.

Given: Zn2+(aq)+ 2e- Zn(s); E° = -0.76 V

Given: Zn²⁺(aq)+ 2e^- Zn(s); E° = -0.76 V
