Chapter 18, Problem 18.5QE

Interpretation Introduction

Interpretation:

Four species which can reduce ${\text{Al}}^{\text{+3}}\text{to}\text{Al}$ has to be listed.

Concept introduction:

Electrochemical series:

It is a decreasing order of the reduction potentials. The most positive ${\text{E}}^{\text{0}}$ are placed in the top in the electrochemical series; it has greater tendency for reduction and lower tendency of oxidation. And the most negative ${\text{E}}^{\text{0}}$ values of elements are placed in the bottom of the series.
