because it not infected and non-perishable
Zinc reacts more than tin, also zinc reacts with tomatoes while tin reacts with only powerful acids. thats why it has been used tin instead of zinc which is more reactive.
Food cans are coated with tin instead of zinc because zinc is more reactive than tin. Tin is only reactive to powerful acids such as tri-sodium phosphate while zinc can be reactive to something like tomatoes.
There are two major uses for it. It is used to coat food cans, to keep them from rusting. Tin has low toxicity, so you can safely store food in tin-plated steel cans. It is also used to make solder, which is used to join electrical components into circuits.
zinc is more reactive than tin and so the food would be continated as the zinc would react with the food and would taste disgusting.
No; they are tin plated.
A tin used for food packaging is actually tin-plated steel. So if the tin wears off, the steel beneath will rust.
no. but tin (Sn) can make cans zinc is used to make dry cells or batteries
You live in the US, pennies that have been made after 1982 are entirely made of zinc (97.5 percent zinc), which has been copper-plated (2.5 percent copper).If however you don't live in the US, galvanized nails are often plated in a layer of zinc.----------- Objects from brass (copper-zinc alloy)- Objects from zinc-plated sheets- Some cosmetics and dermatological creams contain zinc oxyde - ZnO
Zinc and Tin
1810 Peter Durand gets a patient from King George III for a tin-plated can as a food container. At the time cans were made of iron and coated with a thin layer of tin. They were only able to produce 60 cans a day. Today millions are made a day.
Across southern Africa, in general, they're made of tin or tin-plated steel.
because they are tin and they are strong
Because steel will react with the food and could oxidize (Rust), which could penetrate the can and allow in bacteria to contaminate the food.Actually most modern "tin" cans contain no tin, the steel is coated with a protective layer of plastic instead.
