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. In a beaker boil distilled water and add crude benzoic acid, after this pass the solution through the funnel to extract out the impurities. Let the filtrate come down to room temperature itself and you will notice that white crystals of benzoic acid are being formed. Again, filter the solution to take out all your crystals.
By using harmful chemical and solutions, food products are being adulterated which has a severe effect on human health. Thus, through this experiment for your class 11 project, you will get to know about the intensity as well as the chemical substance that is used to adulterate the food. You can take products like milk, ghee, flour, edible oil, pulses, etc; to which you have to add either concentrated or diluted HCl. For the experiment take Arhar Dal, HCl, test tube, etc. Add some dal in the test tube and add distilled water. Carefully shake the solution and let it rest. Add a few drops of concentrated HCl to the test tube and if you see pink colour, there is the presence of adulterant Metanil Yellow. For your project, you can record these observations.
Thus, we hope that through this blog, you are now familiar with the best topics and ideas for chemistry projects for class 11.

Observations and results What happened when you ran the magnet over the whole cereal flakes What happened when you passed the magnet over the crushed cereal powder How much iron were you able to extract from your cereal Were you able to get more by dissolving the cereal powder in water Check the nutrition facts label to see how much iron each serving actually contains (keep in mind that this tabletop project might not be able to get all of the iron out of the cereal).
As it is in Earth's rocks and soil, the iron in your breakfast cereal is attached to the other substances around it. But when you crush the cereal down, it helps to free up the iron particles, so they can be picked up by the magnet (dissolving the other parts of the cereal frees up the iron even more).

To measure the amount of copper present in the solutions that are used to clean the pennies, you will perform a color-based chemical test. The chemicals for the test are contained in a small tablet, which is dissolved in water. If copper is present, the solution will change into a different color depending on the copper concentration. There are additional tests in the kit for iron which you can use for other experiments, but this experiment focuses on the copper test. If you are interested in trying this chemistry science fair project, search your house or your parents' car for some old pennies and let's get started!

Question-11i) Among iron and aluminium which rusts easilyii) What are the conditions, necessary for rusting of ironSolution:i) Among iron and aluminium, iron rusts easily. It forms Al2O3. That is why iron pipes are wrapped with aluminium metal to prevent rusting of iron.ii) 1) Air or oxygen 2) Water, containing dissolved air.These are necessary conditions for rusting of iron.
DIPRA has four free web-based calculators that are useful tools for designing and specifying Ductile iron pipe. Each program is based on the equations and procedures found in corresponding DIPRA technical publications.
In some situations, both below and above ground, it is necessary to install Ductile iron pipe on supports at designated intervals along a proposed pipeline. The Pipe on Supports calculator provides the designer with a way to determine support dimensions and the class of pipe needed to control beam deflection, beam stress and stress at supports.
The Hydraulic Analysis calculator shows how designers can take advantage of the typically larger than nominal inside diameter of Ductile iron pipe compared to other pipe materials. It also computes how that savings in pumping energy also saves in greenhouse gas emissions using an EPA resource based on the location of the project.
This rust-resistant Iron Pillar stands in the middle of Empty Square in Delhi from around 1600 years back. It is older than someone who can expect to non-rusting exposed iron. According to people, this pillar must have become a pile of dust in such long years. People usually think that this Iron Pillar must have come from another place and another time.
Wrought iron pieces are believed to be used for constructing the Iron Pillar. According to a report published, the pillar is rust-free because it has a passive film to protect the iron rust interface. Also, many believed that there is the presence of phosphorus in the metal, and thus, it has adapted according to the existing atmospheric conditions of Delhi. 153554b96e
