What kind of metal is tin?
It is called a "tin" can for a reason. Most are composed of a thin layer of tin over steel. Touch a magnet to it. The tin is less reactive to most foods so it prevents the food from tasting funny. It also prevents the steel from rusting. Some acidic foods, such as pineapple and tomatoes, have cans with a zinc or plastic coating inside to prevent the acid from reacting with the metal.
How could a recycling center separate a mixture of metal cans?
They can seperate a mixture of metal cans by using a weight sensor (aluminum cans are lighter than tin cans).
Why is tin used to coat cans?
Tin (Sn) is used to coat iron cans because it prevents corrosion as it is less reactive than Iron and hence lower in the Reactivity Series than Iron.
Why do cans rust over time?
because cans are made out metal. metal has a chemical reaction to oxygen. [water has oxygen in it so thats why water rusts when with water] the property of chemical property this is is called reactivity.
What are the raw materials used to make drink cans?
Drink cans are usually made from aluminium - either from new metal or from recycled aluminium cans.
Why you use aluminum foil as aluminum is reactive metal?
Aluminium oxidises when it comes in contact with the air and creates a protective coat on itself.
Why do tin openers have magnets if tin is non-magnetic?
Because it is a TIN coating on the inside of cans of food {today replaced by teflon/plastic} with the majority of metal comprising of steel.
Why doesn't acidic food corrode a metal can before it's opened?
The inside of the cans have a protective coating that prevents or slows deterioration of the metal can by the acids in the food.
What metal used in drink cans that is often recycled?
copper because it isn't a very reactive metal ...... however gold is very least reactive but is is very expensive to buy so go with copper !fruit juice cans are either steel or aluminum, like any other can, but are coated on the inside surface with a thin layer of plastic to keep the metal from reacting to the juice.copper would be very bad as its reaction products are toxic!
Why aren't cans made of pure tin?
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.
Why does a aluminum drinks can not react with the contents?
Most soft drinks are slightly acidic, and aluminium is a very reactive metal -- E0 is -1.7 volt. Why, then, does the can not react with the contents?There are two reasons. Firstly, although aluminium is potentially very reactive, its first reaction is usually to form an impervious layer of aluminium oxide over the whole of its surface, and this ensures its inability to react further. Secondly, just to make sure, most aluminium drink cans are coated on the inside with a thin film of unreactive plastic.

Why is aluminium a good metal to use for drinks cans?
Aluminum is a good metal for drinking cans because it is light, easily obtained, non-toxic and it can be handled roughly.
What protect the inside of the metal cans?
tin is used to protect the inside of metal cans

What is the basis of long life of pickles and jams?
The pH of jams and pickles are very low and could react with the metal in cans. Glass is less reactive and is generally used for acid foods.
