Chapter 16, Problem 83E

Interpretation Introduction

Interpretation: The metals that dissolve in $\text{HCl}$ are to be determined. For the dissolved metals, a balanced redox reaction is to be written that shows the dissolution of metals.

Concept Introduction: The loss of electron is termed as oxidation.

The gain of electron is termed as reduction.

When oxidation and reduction simultaneously takes place, then it is known as redox reaction.

In balanced redox reaction, each of the atoms on both sides of reactions is equal.

In the activity series of metals, the most reactive metals are present at the top of the list.

Metals that lie above ${\text{H}}_{\text{2}}$ in activity series dissolve in acids.

Metals that lie below ${\text{H}}_{\text{2}}$ in activity series do not dissolve in acids
