Answer 1

Higher the value of standard reduction potential of a compound, it will have strong tendency to get reduced and oxidize the other compound. The compound with higher reduction potential will be stronger oxidizing agent.

Zn²⁺(aq) + 2e^-$\rightarrow$Zn(s). E° = -0.76V

Fe2+(aq) +2e^-$\rightarrow$Fe(s) . E° = -0.44V

(1) the stronger oxidizing agent is Fe²⁺(aq). (Answer)

H2O2 +2H⁺ + 2e^-$\rightarrow$ O₂ + 2H₂O . E° = 1.78V

O₃ + 2H⁺ + 2e^-$\rightarrow$ O₂ + H₂O. E° = 2.07V

(2)the stronger oxidizing agent is O₃(g). (Answer)

Cl₂(g) + 2e^-$\rightarrow$2Cl^-(aq). E° = 1.36V

2HClO(aq) + 2H⁺ + 2e^-$\rightarrow$ Cl₂ + 2H₂O. E° = 1.63V

(3) the stronger oxidizing agent is HClO(aq) . (Answer)

F₂(g) + 2e^-$\rightarrow$2F^-(aq). E° = 2.87V

I₂(s) + 2e^-$\rightarrow$ 2I^-(aq). E° = 0.54V

(4) the stronger oxidising agent is F₂(g) . (Answer)
