They can be obtained from a hardware store. They should be cleaned of rust prior to the experiment. This can be achieved with dilute about 1 M hydrochloric acid, followed by thorough rinsing in cold water.
Highlight text to annotate it X Iron Nails kept in Copper Sulphate Solution Just as atoms and ions combine in very specific ways, molecules and compounds react with each other in definite quantities. A chemical reaction is a process that is characterised by a chemical change in which one set of chemical substances transform into another.
Chemical reactions can be divided into combination reaction, decomposition reaction, displacement reaction and double displacement reaction; each having comparable characteristics. A combination or synthesis reaction involves the combination of two or more substances to make a more complex substance.
The reactants may be elements or compounds, and the product will always be a compound. A decomposition reaction is the opposite of a synthesis reaction in which one substance is broken down into two or more, simpler substances.
In a displacement reaction, a neutral element becomes an ion as it replaces another ion in a compound but in a double-displacement reaction, the ions of two compounds exchange places in an aqueous solution to form two new compounds.
The aim of this experiment is to find the reaction of an iron nail when kept in copper sulphate solution and classify it as combination reaction, decomposition reaction, displacement reaction or double displacement reaction.
Copper sulphate solution, Iron nails, boiling tubes, stands with clamp and a piece of thread. Take two stands with clamps and fix a boiling tube in each stand. Pick one of the iron nails from the watch glass, tie it with a piece of thread and hang it in one of the boiling tubes.
Then tie the other end of the thread to the stand. Take copper sulphate solution in a beaker and pour some of it into both the boiling tubes.
Ensure that the iron nail hung in the boiling tube is completely immersed in the copper sulphate solution. Now, keep the apparatus undisturbed for a day.
After one day, remove the iron nail immersed in the solution and place it in the watch glass. Compare the two iron nails placed in the watch glass. We can see a deposit of copper on the iron nail and the copper sulphate solution changes from blue to light greenish colour.
This light greenish solution is known as Iron Sulphate or Ferrous Sulphate. To ascertain the formation of ferrous sulphate solution, add a few drops of ammonium hydroxide into it. We can see that the light greenish solution changes to "dirty green precipitate. The chemical reaction that happened here is a single displacement reaction in which a highly reactive metal displaces a less reactive metal from its solution.Rusting of iron involve a series of reaction.
When metal surface comes in contact with water, the dissolved oxygen reacts with metal like iron causing the formation of iron oxides. Rust is a general term for iron oxides formed by the reaction of iron with oxygen.
Several forms of rust are distinguishable visually, and form under different circumstances. The chemical composition of rust is typically hydrated iron(III) oxide (ashio-midori.com2O), and under wet conditions may include iron(III) oxide-hydroxide (FeO(OH)).
Rusting Nails, Alkaline Water and Alleged Antioxidant Claims This is one of the 'proofs' I received that alkaline water is beneficial to health because it is alleged to be a strong antioxidant, and as everyone knows, antioxidants are beneficial to health. A single displacement reaction takes place, when an iron nail is placed in copper sulfate solution.
The chemical reaction can be written as: Fe (s) + CuSO4 (aq) -> FeSO4 (aq) + Cu (s) In this case, iron, being more reactive than copper, will displace it from the solution. To perform the reaction of Iron nails kept in copper sulphate solution and classify it on: i. Combination reaction ii.
Decomposition reaction iii. Displacement reaction iv. Double displacement reaction Theory (a) Iron is more reactive than sulphur. Nails rust when they are exposed to oxygen.
The rust is actually iron oxide and forms when the iron in the nail reacts with the oxygen in the air or in liquids. A simple science project tests the effects of different liquids, such as oil, water, vinegar and detergent, on nails.
