Question

Soft drink cans as shown below are usually electroplated with tin because :

• A. Tin is less expensive compared to other metals
• B. Tin is more reactive than other metals that can be used
• C. Tin is stronger and shiny in appearance
• D. Tin is less reactive compared to the base metal with which the can is made.

Answer 1

The correct option is D Tin is less reactive compared to the base metal with which the can is made.

Tin is less reactive than the base metal with which the can is made. It is less likely to undergo corrosion compared to other more reactive metals that could be used for this purpose. Hence, tin is plated on cans to prevent them from corrosion.
