Lower Standard Reduction Potential (SRP) Value
• Standard reduction potential (SRP) is a measure of the tendency of a chemical species to acquire electrons and undergo reduction.
• The more positive the SRP value, the greater the tendency of the species to be reduced.
• The more negative the SRP value, the greater the tendency of the species to be oxidized.
• A lower SRP value indicates a lower tendency to acquire electrons and undergo reduction.
• Therefore, the species with the lowest SRP value will be the one with the least tendency to be reduced.
Comparison of SRP Values
• Mn2+ / Mn has an SRP value of -1.18 V.
• Zn2+ / Zn has an SRP value of -0.76 V.
• Fe2+ / Fe has an SRP value of -0.44 V.
• Ni2+ / Ni has an SRP value of -0.25 V.
Explanation
• From the above comparison, it is evident that Mn2+ / Mn has the most negative SRP value (-1.18 V), indicating that it has the least tendency to be reduced.
• Hence, the correct answer is option 'A' - Mn2+ / Mn has a lower SRP value compared to the other options.
