Experiment No. 3: Electrochemistry and Corrosion Date Performed: November 4‚ 2010 CONCLUSION Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor and an ionic conductor and which involve electron transfer between the electrode and the electrolyte or species in solution. Basically‚ an oxidation-reduction reaction (redox reaction) is a reaction in which electrons are transferred between species or in

Electrolytes accelerate the corrosion process when combined with water‚ similar to the rusting that occurs on vehicles due to road salt in winter conditions. In this experiment‚ our group will demonstrate how a chemical reaction from vinegar‚ water‚ and bleach can accelerate the rusting process of steel. If steel wool pads are submerged in bleach‚ water‚ and vinegar‚ then the steel wool pads will rust faster in water because Electrolytes accelerate the corrosion process when combined with water

’The corrosiveness of guilt’. Discuss in relation to ’Macbeth’. Guilt is a prominent factor in Macbeth and it is experienced by various characters throughout the progression of the play. It could be said that guilt is corrosive but to what extent is open to interpretation. In relation to Macbeth‚ it breaks away at his sanity however it doesn’t do so to an extent to drive him to commit suicide as it does to Lady Macbeth. Although Macbeth was written at a time before the introduction of Gothic literature

predict that adding NaCl to the test tube with water and air will promote rusting of the iron nail. Background information: Rusting is the chemical reaction between a metal and oxygen in the presence of water. In this case‚ it is the corrosion of iron. Corrosion is defined as the loss of metallic properties of a metal due to oxidation and it results in them losing strength and electrical conductivity. When iron is in contact with water and oxygen‚ it will rust. Chemical equation of the rusting

Q I am contemplating powder-coating some hot-dip galvanized steel to further increase its corrosion protection. I have heard some rumors regarding the adhesion of powder coatings on galvanized steel. Apparently the adhesion is compromised due to the zinc coating outgassing. Is there any truth to this? Is there anything I can do to prevent outgassing of the zinc coating? lightly-acidic solution will remove oxides from the surface as well as slightly etch the steel surface‚ providing a better surface
