Chapter 20, Problem 30E

Interpretation Introduction

Interpretation: The balanced equation to describe the reaction of aluminum metal with concentrated aqueous sodium hydroxide is to be stated.

Concept introduction: Aluminum $\left(\text{Al}\right)$ is a group $3\text{A}$ element and exhibits $+1$ and $+3$ oxidation state. It has a high electrical conductivity.

The reaction that shows the transfer of electrons between two species is known as the redox reaction.

To determine: The balanced equation to describe the reaction of an aluminum metal with concentrated aqueous sodium hydroxide.
