Explanation:

Iron and steel rust when they come into contact with water and oxygen. They rust faster in salty water or acid rain. Aluminium, on the other hand, does not corrode easily, because its surface is protected by a layer of aluminium oxide.

The following experiment investigates the conditions necessary for rusting to occur.

Fill up test tubes as follows:

Test tube A is filled with boiled water and an oil layer so that there is no oxygen.

Test tube B has calcium chloride which will dry the air.

Test tube C has regular tap water that has oxygen.

Place an iron nail in each of the three test tubes.

Cover each test tube and let it stand for a couple of days.

Compare the conditions of the nails in each test tube.

observation:the iron nail of only test tube c rusts because it was exposed to oxygen and moisture

conclusion:oxygen and moisture cause rusting.

Answer:

Leave the three test tubes in this way for a few days and observe them. You will see that nails in test tubes X and Y are rust-free, whereas the nail in the test tube Z contains rust. This experiment shows that air (oxygen) and water (or moisture) both are required for rusting of iron.
