Consider only the species (at standard conditions) Na + , Cl − , Ag + , Ag, Zn 2+ , Zn, Pb in answering the following questions. Give reasons for your answers. (Use data from Table 17-1.) a. Which is the strongest oxidizing agent? b. Which is the strongest reducing agent? c. Which species can be oxidized by SO 4 2− ( aq ) in acid? d. Which species can be reduced by Al( s )?

Interpretation:

Different chemical species are given. Various questions based on oxidizing and reducing power of these species based on the value of reduction potential are to be answered.

Concept introduction:

The species with higher value of reduction potential has more tendencies to undergo reduction and therefore, it oxidizes the other species while the species with lower value of reduction potential has more tendencies to undergo oxidation and therefore, it reduces the other species.

To determine: The strongest oxidizing agent among the given species.

The strongest oxidizing agent among the given species is Ag+ .

The species that can undergo reduction are,

Na++e−→Na   E°=-2.71 VZn2++2e−→Zn   E°=−0
