Homework Answers
(answer) 2 and 3 is correct (option-3)
explanation;
1) H+ capable of oxidizing Cu to Cu2+ - it is not correct.
because , standard reduction potential value of H+/H is 0V and Cu2+/Cu is + 0.34V. standard reduction potential of hydrogen is more negative than copper . so it cannot oxidize Cu to Cu2+
2) Fe3+ is capable of oxidizing I- to I2 - it is correct.
because, standard reduction potential value of Fe3+/Fe2+ is 0.77V and for I2/I- is 0.53 V. here standard reduction potential of Fe3+ is more positive. so it can oxidize the I- to I2.
3) H2 is capable of reducing Ag+ to Ag - it is correct.
because, reduction potential of Ag+ to Ag is 0.8V and reduction potential of H+ to H2 is 0V. reduction potential of Ag is larger than reduction potential of H+ . so H2 can reduce Ag+ to Ag.

Which of the following species is the strongest oxidizing agent under standard state conditions
Which of the following species is the strongest oxidizing agent under standard state conditions? a. Ag+(aq) b. H2(g) c. H+(aq) d. Cl2(g) e. Al3+(aq) An oxidizing agent is a substance that gains electrons in a redox chemical reaction. I think Al3+ has a very high electron affinity and should pull electrons to it in a chemical reaction. Is Al3+ the best choice for this problem?
