Which of the following species is the strongest oxidizing agent under standard-state conditions?

Question

Quizplus · Accepted Answer

Chlorine gas (Cl2) has a standard reduction potential of +1.36 V, which means it has a very strong tendency to gain electrons and be reduced (i.e. it is a weak oxidizing agent). However, when it is ionized to form chloride ions (Cl-), its reduction potential decreases to -1.36 V, meaning it has a strong tendency to lose electrons and be oxidized (i.e. it is a strong oxidizing agent). Thus, the species Cl2(g) -> 2Cl-(aq) is the strongest oxidizing agent under standard-state conditions. Among the given choices, option D represents Cl2(g), so it is the correct answer.
