Chapter 8, Problem 8.20E

Interpretation Introduction

Interpretation:

Whether addition of powdered zinc metal to a solution of ${\text{Al}}^{3+}$ precipitates out aluminum or not is to be demonstrated electrochemically.

Concept introduction:

The reduction potential of species measures its tendency to get reduced. The reduction potential is inverse of oxidation potential. If a species has high reduction potential, then it has low tendency to get oxidized. If a species has low reduction potential, then it has high tendency to get oxidized.
