Question

what happens when iron reacts with air and water . class 10















please give the answer in short.​

Answer 1

Answer:

corrosion is the formation of metal oxide when exposed to moist air .rust is iron oxide . corrosion occures in the presence of moisture.for example:when an iron is exposed to moist air, it react with oxygen to form rust (Fe2O3.xH2O)

Answer 2

Air-free water has little effect upon iron metal. However, iron metal reacts in moist air by oxidation to give a hydrated iron oxide. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner.
