Question

In the corrosion process, it is the cathodic area or dissimilar cathodic material that corrodes.

A) Cathodic area
B) Dissimilar cathodic material
C) Both cathodic area and dissimilar cathodic material
D) Anodic area
In the Galvanic or Electro-Chemical Series for metals, the most anodic metals are those that will give up electrons most easily.
A) True
B) False

Answer 1

The anodic area corrodes during corrosion, not the cathodic area. In the Electro-Chemical Series, the most anodic metals give up electrons most easily, which is true.

Step-by-step explanation:

In the corrosion process, it is the anodic area that corrodes, not the cathodic area or the dissimilar cathodic material. Thus, the correct answer to the first question is D) Anodic area.

Regarding the Galvanic or Electro-Chemical Series for metals, it is indeed true that the most anodic metals are those that will give up electrons most easily. Therefore, the answer to the second question is A) True. This is because anodic metals have a higher tendency to undergo oxidation, which means losing electrons and corroding in the process.
