For a redox reaction, if the standard reduction potentials are E°(A/B) = 0.80 V and E°(C/D) = 0.40 V, which species is the stronger oxidizing agent?
Step 1: Understand what a redox reaction is. It involves the transfer of electrons between two species.
Step 2: Know that in a redox reaction, the species that gains electrons is called the oxidizing agent.
Step 3: Look at the standard reduction potentials given: E°(A/B) = 0.80 V and E°(C/D) = 0.40 V.
Step 4: Compare the two standard reduction potentials. A/B has a higher value (0.80 V) than C/D (0.40 V).
Step 5: Conclude that the species with the higher reduction potential (A/B) is the stronger oxidizing agent.
Standard Reduction Potentials – The standard reduction potential (E°) indicates the tendency of a species to gain electrons and be reduced; higher values correspond to stronger oxidizing agents.
Redox Reactions – Redox reactions involve the transfer of electrons between species, where oxidation refers to loss of electrons and reduction refers to gain of electrons.
