Textbook Problem

Which of the following is the best reducing agent: F2, H2, Na, Na+, F? Explain. Order as many of these species as possible from the best to the worst oxidizing agent. Why can’t you order all of them? From Table 17-1 choose the species that is the best oxidizing agent. Choose the best reducing agent. Explain.

Interpretation Introduction

Interpretation:

The reducing and oxidizing power of the given elements F2,H2,Na,Na+,F is to be stated.

Concept introduction:

The species with higher reduction potential has more tendency to undergo reduction and therefore, it acts as a better oxidizing agent, while the species with lower reduction potential has more chances to undergo oxidation and therefore it acts as a reducing agent.

To determine: The best reducing agent among the stated elements; the order of the species from the best to the worst oxidizing agent; the impossible arrangement of all the species; the best oxidizing and reducing agent from the Table 171 .

Explanation

The best reducing species is the one which has lower reduction potential. As Na has lower value of reduction potential, therefore it acts as the best reducing agent among the given species.

The equations for the reduction of various given species can be represented as follows,

F2+2e-2F-cell=2.87VH2+2e-2H-cell=-2.23VNa++e-Nacell=-2.71V

The value of E°F/F2=2.87V and E°Na/Na+=2.71V . This shows that Na has more tendency to undergo oxidation and therefore it easily reduces the other species
