Rusting of iron nails. The amount of rust increases almost in proportion to the amount of salt added. The magnesium also pushes electrons onto the iron improving its ability to reduce water meaning the pink colour rapidly forms around the entire nail. This video is a science experiment in which we want to know in which condition does the nail rust the fastestthis video is made by Kay Vanessa Raymond Nael.
Take 10 pieces of iron nails free from rust. This science experiment is all about controlling variables to explore which material will rust an iron nail first. This is a 12 increase showing that adding 1g of salt to iron nails in 10ml of water causes a production of rust that is 125 the weight of the submerged iron nails.
Make sure the nails are not galvanised electroplated as they will not rust although galvanised types are usually required as well. In the case of iron rusting the new compound is called iron oxide also known as rust. For rusting to occur you need moisture and oxygen as rusting is due to the formation of iron oxide Fe2O3.
Since the iron oxide is a bulkier molecule than the original iron it takes up more space and this distorts the shape of the nail as it rusts. Rusting is the common term for corrosion of iron and its alloys such as steel. Rustingis the common term for corrosion of iron and its alloys such as steel.
Rusting of iron can be prevented by applying grease or oil. Many other metals undergo similar corrosion but the resulting oxides are not commonly called rust. I want to help you achieve the grades you and I know you are capable of.
Put an iron nail in one test tube and label it A and a steel nail. From this they should be able to conclude that water and air actually oxygen in the air are essential for rusting. If the nail is coupled with a more electro-positive metal like zinc magnesium or aluminium rusting is prevented but if on the other hand it is coupled with less electro positive metals like copper the rusting is facilitated.
