Chapter 17: Problem 1

(a) Briefly explain the difference between oxidation and reduction electrochemical reactions. (b) Which reaction occurs at the anode and which at the cathode?

Short Answer

Expert verified
Answer: In an electrochemical cell, oxidation reaction occurs at the anode and reduction reaction occurs at the cathode.

Step by step solution

01

Understanding oxidation and reduction reactions

Oxidation and reduction reactions refer to the transfer of electrons between chemical species. Oxidation is the process of losing electrons, while reduction is the process of gaining electrons. These reactions are often paired together in what are called redox reactions, where one species is oxidized and another is reduced.
02

Explaining oxidation reactions

Oxidation is a reaction that involves the loss of electrons by a chemical species. When an element is oxidized, its oxidation state increases. This can be represented by the half-reaction: \[A -> A^{n+} + ne^-\] Here, A is the chemical species being oxidized, A^{n+} is the oxidized species, and ne^- represents the number of electrons lost during the oxidation process.
03

Explaining reduction reactions

Reduction is a reaction that involves the gain of electrons by a chemical species. When an element is reduced, its oxidation state decreases. This can be represented by the half-reaction: \[B + me^- -> B^{m-}\] Here, B is the chemical species being reduced, B^{m-} is the reduced species, and me^- represents the number of electrons gained during the reduction process.
04

Identifying reactions at the anode and cathode

In an electrochemical cell, redox reactions occur at the electrodes. The anode is the electrode where the oxidation reaction takes place, while the cathode is the electrode where the reduction reaction occurs. In summary, oxidation happens at the anode and reduction happens at the cathode.

An Fe/Fe \(^{2+}\) concentration cell is constructed in which both electrodes are pure iron. The \(\mathrm{Fe}^{2+}\) concentration for one cell half is \(0.5 M\) and for the other cell half is \(2 \times 10^{-2} M .\) Is a voltage generated between the two cell halves? If so, what is its magnitude and which electrode will be oxidized? If no voltage is produced, explain this result.

(a) What are inhibitors? (b) What possible mechanisms account for their effectiveness?

Briefly describe the phenomenon of passivity. Name two common types of alloy that passivate.

Why does chromium in stainless steels make them more corrosion resistant than plain carbon steels in many environments?

A thick steel sheet of area 100 in. \(^{2}\) is exposed to air near the ocean. After a one-year period it was found to experience a weight loss of \(485 \mathrm{~g}\) due to corrosion. To what rate of corrosion, in both mpy and \(\mathrm{mm} / \mathrm{yr}\), does this correspond?
