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-Zn(s). E° = -0.76V

Fe2+(aq) +2e-Fe(s) . E° = -0.44V

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

H2O2 +2H+ + 2e- O2 + 2H2O . E° = 1.78V

O3 + 2H+ + 2e- O2 + H2O. E° = 2.07V

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

Cl2(g) + 2e-2Cl-(aq). E° = 1.36V

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

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

F2(g) + 2e-2F-(aq). E° = 2.87V

I2(s) + 2e- 2I-(aq). E° = 0.54V

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