- Iron is used to strengthen the bridges and automated vehicles. But, iron has a tendency of corrosion and rusting. Therefore, a layer of zinc is electroplated on the iron.
- Hence, R is not the explanation for A; rather A is the explanation for R. The process of electroplating is used in a variety of everyday products. For example, some parts of the car, taps in the bathroom, gas burner, rim of the wheel have a layer of chromium on them. This gives them a shiny appearance and prevents corrosion.

Assertion A: Iron used to strengthen bridges and automated vehicles has a tendency to be easily corroded and rusting.
Reasoning R: To prevent corrosion and rusting, a layer of zinc is electroplated on iron.
Explanation:
The correct answer is option 'B', which states that both assertion A and reasoning R are correct, but R is not the correct explanation for A.
Corrosion and Rusting of Iron:
Iron is a metal that is widely used in construction, including the strengthening of bridges and the manufacturing of automated vehicles. However, iron has a tendency to corrode and rust when exposed to air and moisture.
Corrosion:
Corrosion is a natural process that occurs when metals, such as iron, react with oxygen in the presence of moisture. This reaction forms iron oxide, commonly known as rust. Corrosion weakens the structural integrity of iron, making it unsuitable for applications where strength and durability are essential.
Reasoning R - Electroplating with Zinc:
To prevent the corrosion and rusting of iron, a process called electroplating is often employed. Electroplating involves coating the iron surface with a layer of zinc. Zinc is chosen for electroplating because it is more reactive than iron and readily forms a protective layer.
Protection by Zinc:
When zinc is electroplated onto iron, it acts as a sacrificial anode. This means that the zinc layer corrodes instead of the iron when exposed to air and moisture. The zinc layer forms a barrier between the iron and the environment, protecting the iron from corrosion.
Advantages of Electroplating:
Electroplating with zinc provides several benefits:
1. Corrosion Resistance: The zinc layer prevents direct contact between iron and the corrosive environment, significantly reducing the rate of corrosion.
2. Aesthetic Appeal: Zinc electroplating can enhance the appearance of iron surfaces, making them more visually appealing.
3. Cost-Effective: Electroplating is a cost-effective method of protecting iron from corrosion, as it requires less material compared to other protective coatings.
Limitations of Zinc Electroplating:
While zinc electroplating is an effective method of preventing corrosion on iron surfaces, it is not a permanent solution. The zinc layer can eventually wear off or become damaged, exposing the underlying iron to corrosion. Regular maintenance and reapplication of the zinc coating may be necessary to ensure long-term protection.
Conclusion:
In conclusion, iron used in the construction of bridges and automated vehicles is prone to corrosion and rusting. To prevent this, a layer of zinc is electroplated onto the iron surface. This electroplating process provides corrosion resistance and enhances the durability of iron structures. However, it is important to note that while electroplating with zinc is effective, regular maintenance is required to ensure long-term protection against corrosion.
Reasoning R: To prevent corrosion and rusting, a layer of zinc is electroplated on iron.
Explanation:
The correct answer is option 'B', which states that both assertion A and reasoning R are correct, but R is not the correct explanation for A.
