Record your results again after 48 hours.

Iron nails kept in copper sulphate solution

Write down what liquid is in each container. When something is oxidized, it loses electrons to what is known as a reducing agent. Suggest a possible reason for the observation. Use the stirring rod to help keep the copper in the beaker.

I do not have easy access to reagent grade chemicals or a pH meter, but there are several additional experiment that could be performed to see if: I am working on corrosion in chem at the moment.

Reference The formula for oxidation rusting of iron nails in the jar is: Set the nails aside on a paper towel and allow to air dry, then weigh them on the electronic balance.

I would appreciate it if anyone who reads this article and uses the ideas to create experiments to test the theories presented would send me the results of their experiments. Can you tell me Book, Anita Brandolini, Ph.

When metals rust, it forms metal oxides. Nails and paper clips are made of steel, an alloy primarily composed of iron. Hold a stirring rod in one hand and the beaker in the other. The growth of these tubercles can greatly affect the flow of water through water mains as shown here. Some may float, which is okay.

After one day, remove the iron nail immersed in the solution and place it in the watch glass. Clean up any sanding dust on the table with a slightly damp paper towel. Set up Experiment Place numbered test tubes or cups in a line to let you compare the effects of different liquids on your nails.

You may also weigh each nail at this point. The corrosion of iron, better known as rusting, is an oxidation-reduction process that destroys iron objects left out in open, moist air. Electrons flow through the metal, like electricity through a wire, from the site where iron is oxidized to the site where oxygen is reduced.

Salt in the water speeds up the oxidation process by acting as a catalyst.

Iron Nails and Copper Chloride Reaction.. Is it Fe 2+ or 3+?

Oxygen then reacts to the positively charged iron and creates ferrous oxide. Conclusions and observations I would draw from this first experiment would be: The silvery color of iron turns to reddish-brown due to formation of hydrated oxide which is known as rust and the process is called as rusting.

If water is added the rusting occurs more rapidly. On the surface this looks like a straightforward demonstration of the antioxidant properties of alkaline water: Pull the nails out of the solution and rinse them off, keeping the rinse water in the beaker. Mole is abbreviated "mol".

In these instances customers do not recognize marketing presentation as deception and are unwittingly paying for a product that does not perform as advertised.

He presents pictures of ice crystals to prove this claim: In the photograph above the steel wool that was in the tea is on the left and steel wool that had been in plain water is on the right.

We can see that the light greenish solution changes to "dirty green precipitate.I took iron nails and put them in a container filled with muriatic acid (chemicals for my pool). The acid contains an equivalent of concentrated HCl since it is composed of HCl by %.

The other % is listed simply as "other ingredients". Using a chemical reaction between iron and copper(II) chloride, determine the number of (a) moles of iron that react and (b) moles of copper produced. Brief Overview The chemical reaction to be used is this: Fe(s Obtain two iron nails and a small piece of sandpaper.

Well, this is a redox reaction, that would ultimately give ferric oxide. An astonishing amount of resources is devoted to rust prevention, so as our bridges and buildings do not fall down.

3 - Rust and rust-protection Rusting is an oxidation reaction in which Iron picks up Oxygen. We could show the result of sacrificial protection in College by putting Iron nails in water to rust and attaching some to more reactive metals, some to less reactive metals and leaving some alone.

Jun 07,  · The iron is greater reactive than copper so whilst the iron nail is immersed in copper sulphate the iron takes sulphate ion from the copper sulphate and copper metallic is deposited on suited of the iron so as that the nail will then look like a copper agronumericus.com chemical reaction is termed a alternative reaction, and is chemically represented as: CuSO4(compound in answer) + Fe(metallic Status: Resolved.

Galvanic corrosion (also called bimetallic corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices.
