Step 1
Identify the Region and Reaction at X
Answer
To determine the type of region at X, we need to evaluate the reactions taking place. The anode is where oxidation occurs, while the cathode is where reduction happens. Examining the options:
-
Option A: This reaction represents oxidation as iron is being oxidized to iron ions, which identifies this as a reaction at the anode.
-
Option B: This is a similar reaction indicating that the cathode isn't accurately represented here since this describes an oxidation process.
-
Option C: This represents a reduction, indicating that this reaction occurs at the cathode, converting oxygen and protons to hydroxide ions.
-
Option D: This is also a reduction reaction occurring at the cathode with oxygen.
Given that both A and C represent oxidation and reduction respectively, the answer is A, indicating the region at X is the anode where the reaction involves oxidation of Fe(s).
