Exemplary Rusting Iron Experiment
Galvanising is when the iron is coated with a layer of zinc.
Rusting iron experiment. The exposure of iron or an alloy of iron to oxygen in the presence of moisture leads to the formation of rust. Perhaps the most familiar example of corrosion is the rusting of iron. It also presents that rusting is faster in salty water.
In the case of iron rusting the new compound is called iron oxide also known as rust. Iron water oxygen hydrated iron III oxide Iron and. Take 10 pieces of iron nails free from rust.
The iron reacts with water and oxygen to form hydrated iron III oxide which we see as rust. This protects the iron by barrier method. Galvanization involves coating an iron object with a protective layer of zinc which helps prevent that reaction or slow it way down.
Before conducting the actual experiment and receiving credible data I can hypothesize that as the temperature in degrees Celsius of the environment in which the iron nails are kept increases the rate of corrosion of the iron nail will also increase. Given sufficient time oxygen and water any iron mass will eventually convert entirely to rust and disintegrate. When some grease or oil is applied to the surface of an iron object then air and moisture cannot come in contact with it and hence rusting is prevented.
During the rusting of iron oxygen from the air reacts with it to form iron oxide and at the same time this iron oxide combines with water to form hydrated iron oxide. Rust consists of hydrated iron III oxides Fe2O3nH2O and iron III oxide hydroxide FeO OH Fe OH3. The final product of iron oxidation rust is usually a ferric oxide often hematite Fe 2 O 3.
Half fill two test tubes with water. Even if you dont want to stud. ZnCO 3 is formed when zinc reacts with oxygen in the air.
