(a)

Interpretation Introduction

Interpretation: The reduction of ${\text{Ag}}^{+}$ to $\text{Ag}$ by hydrogen under standard conditions is to be validated.

Concept introduction: Hydrogen can reduce those elements that have more positive standard reduction potential than hydrogen.

To determine: If ${\text{Ag}}^{+}$ could be reduced to $\text{Ag}$ by hydrogen gas under standard conditions.

(b)

Interpretation Introduction

Interpretation: The reduction of ${\text{Mg}}^{+2}$ to $\text{Mg}$ by hydrogen under standard conditions is to be validated.

Concept introduction: Hydrogen can reduce those elements that have more positive standard reduction potential than hydrogen.

To determine: If ${\text{Mg}}^{+2}$ could be reduced to $\text{Mg}$ by hydrogen gas under standard conditions.

(c)

Interpretation Introduction

Interpretation: The reduction of ${\text{Cu}}^{+2}$ to $\text{Cu}$ by hydrogen under standard conditions  is to be validated.

Concept introduction: Hydrogen can reduce those elements that have more positive standard reduction potential than hydrogen.

To determine: If ${\text{Cu}}^{+2}$ reduced by hydrogen to $\text{Cu}$ by hydrogen gas under standard conditions.

(d)

Interpretation Introduction

Interpretation: The reduction of ${\text{Cd}}^{+2}$ to $\text{Cd}$ by hydrogen gas under standard conditions is to be validated.

Concept introduction: Hydrogen can reduce those elements that have more positive standard reduction potential than hydrogen.

To determine: If ${\text{Cd}}^{+2}$ could be reduced to $\text{Cd}$ by hydrogen gas under standard conditions.
