(a)
Interpretation: To interpret the metal that can be reduced more readily between the following metal pairs.
Concept Introduction: A series of elements in which they are placed in an order of standard electrode potential is known as activity series.
(a)
Answer to Problem 127A
The metal that is more readily reduced is copper.
Explanation of Solution
In an activity series, the more active metal is the one that is readily oxidized. The substances, that are strong reducing agents (negative standard reduction potential) than hydrogen is placed above hydrogen in the activity series while the weaker reducing agents (positive reduction values) than hydrogen are placed below hydrogen in this series.
So, between copper and magnesium, the one that is placed below hydrogen in the activity series is copper.
Thus, the metal that is more readily reduced is copper.
(b)
Interpretation: To interpret the metal that can be reduced more readily between the following metal pairs.
Concept Introduction: A series of elements in which they are placed in an order of standard electrode potential is known as activity series.
(b)
Answer to Problem 127A
The metal that is more readily reduced is nickel
Explanation of Solution
In an activity series, the more active metal is the one that is readily oxidized. The substances, that are strong reducing agents (negative standard reduction potential) than hydrogen is placed above in the activity series while the weaker reducing agents (positive reduction values) than hydrogen are placed below in this series.
So, between cadmium and nickel, in the activity series, cadmium metal is placed above nickel metal.
Thus, the metal that is more readily reduced is nickel.
(c)
Interpretation: To interpret the metal that can be reduced more readily between the following metal pairs.
Concept Introduction: A series of elements in which they are placed in an order of standard electrode potential is known as activity series.
(c)
Answer to Problem 127A
The metal that is more readily reduced is silver.
Explanation of Solution
In an activity series, the more active metal is the one that is readily oxidized. The substances, that are strong reducing agents (negative standard reduction potential) than hydrogen is placed above in the activity series while the weaker reducing agents (positive reduction values) than hydrogen are placed below in this series.
So, between silver and tin, the one that is placed below hydrogen in the activity series is silver.
Thus, the metal that is more readily reduced is silver.
(d)
Interpretation: To interpret the metal that can be reduced more readily between the following metal pairs.
Concept Introduction: A series of elements in which they are placed in an order of standard electrode potential is known as activity series.
(d)
Answer to Problem 127A
The metal that is more readily reduced is iron.
Explanation of Solution
In an activity series, the more active metal is the one that is readily oxidized. The substances, that are strong reducing agents (negative standard reduction potential) than hydrogen is placed above in the activity series while the weaker reducing agents (positive reduction values) than hydrogen are placed below in this series.
So, between zinc and iron, in the activity series, zinc metal is placed above iron metal.
Thus, the metal that is more readily reduced is iron.
(e)
Interpretation: To interpret the metal that can be reduced more readily between the following metal pairs.

So, between cadmium and nickel, in the activity series, cadmium metal is placed above nickel metal.
Thus, the metal that is more readily reduced is nickel.

The substances, that are strong reducing agents (negative standard reduction potential) than hydrogen is placed above in the activity series while the weaker reducing agents (positive reduction values) than hydrogen are placed below in this series.
So, between aluminum and copper, the one that is placed below hydrogen in the activity series is copper.
Thus, the metal that is more readily reduced is copper.
