Tin cans used for food storage are made by:
AMelting tin and casting the can in one piece
BPainting the steel surface with shiny silver paint
CElectroplating a thin layer of tin on a steel base — tin is non-reactive with food while steel gives strength
DCoating the whole can in plastic
Answer & Solution
Correct answer: C. Electroplating a thin layer of tin on a steel base — tin is non-reactive with food while steel gives strength
Tin is non-toxic and does not react with most foods, so it is safe for direct food contact. Steel is strong and cheap but rusts and reacts with food. Electroplating a thin tin layer onto a steel can combines steel's strength with tin's food-safe surface.
