Iron is one of the widely distributed elements in the nature. One of its striking characteristics is that it undergoes rusting on combining with water, air & carbon-dioxide due to which its surface gets covered with a red brown flake coating called "RUST". RUST is affected by moisture, oxygen & carbon - dioxide. RUST is soft and porous and it gradually falls off from the surface of iron material. It is a continuous process and it gradually eats up iron due to which an iron object loses its strength. It is very wasteful process and should be prevented. It is very-very slow process.
The Rusting of Iron. Aim: To find out the special name given to the corrosion of iron. To find out the two stages involved in the rusting of iron. Iron is the most widely used metal and the rusting of iron (and steel) costs millions of pounds each year.
In this practical, students put iron nails in various conditions including wet, dry, air-free and salty to find out what causes iron to rust. The experiment will need to be set up in one lesson and then left for more than 3 days before being re-examined. It could be left set up for longer if necessary.
They should see that the nails in tubes 2 and 4 do not rust. The nail in tube 3 rusts the most. From this they should be able to conclude that water and air (actually oxygen in the air) are essential for rusting. Salt can increase the rate of rusting. This can lead to a discussion about rust protection and methods which can be used to keep air and water away from the iron such as paint, grease and plastic coating.
Metals and alloys undergo rusting and corrosion. The process by which some metals when exposed to atmospheric condition i.e., moist air, carbon dioxide form undesirable compounds on the surface is known as corrosion, The compounds formed are usually oxides . Rusting is also a type of corrosion but the term is restricted to iron or products made from it .Iron is easily prone to rusting making its surface rough. Chemically, rust is a hydrated ferric oxide
2) Galvanization ; The metallic iron is covered by a layer of more reactive metal such as zinc. The active metal losses electrons in preference of iron. Thus, protecting from rusting and corrosion.
It is clear from the observation that coupling of iron with more electropositive metals such as zinc and magnesium resists corrosion and rusting of iron. Coupling of iron with less electropositive metals such as copper increases rusting.
Rusting of iron is amongst one of the most interesting chemistry projects for class 11 that lets you learn about a very important example of chemistry in everyday life. As the phenomenon of rusting takes significant time, thus, for this Class 11 chemistry project, you will be completing this in terms of chemical reactions. To complete the project, you will be needing some iron nails, boiling tubes, rubber band, sodium chloride, distilled water, edible oil, etc. The main basis of your project will be the reaction of iron with moisture. For the experiment, place the nails in 4 test tubes and some distilled water in 1st tube, distilled water with salt in 2nd tube, boiled distilled water in 3rd tube along with edible oil and calcium chloride in the 4th one. Seal the test tube for a few days and you will notice that the nails in 1st and 2nd tubes are now corroded.
Different chemical substances or organic compounds are extracted from various sources and may contain some amount of impurity. Amongst the prominent chemistry projects for class 11, this one carries out a thorough analysis of impurities. The experiment for this project will include crystallization of solutions like copper sulphate, benzoic acid, alum, etc. We will begin by crude benzoic acid, distilled water, cold water, beaker and funnel, filter paper, glass rod, test tubes, etc
