Question

In .................. process, a layer of molten tin is deposited on metals.

• A. Anodization
• B. Tinning
• C. Galvanizing
• D. Alloying

Hint:

Tinning is a process where a thin layer of tin is applied to metal surfaces to prevent corrosion. It is different from galvanizing, which uses zinc instead of tin.

Answer 1

The Correct Option is B

Step 1: Understanding the process of tinning
Tinning is the process of coating a metal, usually iron or steel, with a thin layer of molten tin to prevent corrosion and enhance durability. Step 2: Why tinning is used
- Tin is corrosion-resistant and protects the base metal from rusting. - It is commonly used for food containers, kitchen utensils, and electrical components. Step 3: Evaluating the given options
- Anodization: Electrochemical process used to thicken the oxide layer on metals like aluminum, not related to tin coating.
- Tinning: Correct choice as it involves applying molten tin to a metal surface.
- Galvanizing: Coating metal with zinc, not tin.
- Alloying: Mixing metals to form an alloy, not a coating process.
Thus, the correct answer is Tinning.
