Cool Rusting Of Iron Nail Experiment

An aqueous solution of detergent or some acetone can be used to degrease the iron nails before the experiment.

Rusting of iron nail experiment. Another way to prevent the corrosion of iron is to exclude oxygen and moisture from its surface with a protective coating. Corrosion is the degradation of a metal due to chemical reactions between it and its surrounding environment Bell 2015. Rusting is the oxidation of metal whereby the oxygen in the environment combines with the metal to form a new compound called a metal oxide.

Phenolphthalein turns pink in the region where oxygen is taking electrons. Half fill two test tubes with water Put an iron nail in one test tube and label it A and a steel nail in another tube label it B Put an iron nail in a dry test tube and label it C and plug with a small piece of cotton wool on which a few pieces of calcium chloride are placed. This experiment indicates that the corrosion of iron involves oxidation.

Sodium chloride powder 3. Dependent Amount of rust formed mass of nail Controlled Amount of rust on nail to prevent self-shielding Uncontrolled Temperature Amount of oxygen entering the solution Volume of solution due to evaporation 2 Planning B 21 Materials Required 1. I think the iron will rust faster in the salt water than the fresh water and vinegar.

Clean iron nails should be used. Purpose of the Experiment. The nail covered with zinc did not rust at all.

Calcium chloride is a. To know what affects the reaction rate. Iron water oxygen.

My conclusion is that my hypothesis partially correct. I also think the color of the water will change to the rusty color. Magnesium ribbon and the copper wire should be used to wrap around the iron nail.
