Question
Why are cans typically electroplated with tin when used to store soft drinks or food items?
- Tin is less reactive than the metal the can is made of.
- Tin is lighter than other metals.
- Tin is strong and shiny
- Tin is cheap.
Hint:
The cans that are used to store food items are electroporated by tin as the can is made up of reactive metals and the tin is less reactive than the metal.
The correct answer is: Tin is less reactive than the metal the can is made of.
- The can is made up of metals that react with soft drinks.
- By electroplating the can with tin, the reaction between the metal and stored items can be prevented.
- The tins are less reactive than the metals.
