A galvanized nail or screw has a zinc (obviously) finish. Rusting Nails student experiment and research. Aluminium Foil Some changes were observed. We investigated the experiment over 14 days (2 weeks). Compare what is in the water with the corrosion results. The nails in tube “A” should remain rust-free, while the nails in tube “B” should begin to rust. It is most commonly associated with rust, in particular the rusting of metals such as iron. 2002. Corrosion is an oxidation-reduction (redox) reaction in which a free metal is oxidized, or “corroded,” by some oxidizing agent. To demonstrate that galvanic anodes through cathodic protection may also eliminate destructive galvanic corrosion, repeat experiment (e) using a partially copper plated nail in place of the bare iron nail. 4. Compare the results with those of experiment (b). Iron corrosion… Rusting occurs in nail ‘1’, but not in nail ‘2’. Corrosion of Iron Experiment. Experiment involves the corrosion of nails in Coke, lemon juice, oil and water. Over the next week, observe your experiment and record your observations. This website and its content is subject to our Terms and Conditions. In the test tube A pour some water and close its mouth with the help of a cork. Theory: Corrosion is the degradation of a metal due to chemical reactions between it and its surrounding environment (Bell, 2015). Q. HELP! The aluminium foil got lighter in color and started to fade, disintegrate and fall apart in a few places. A discussion started in 2002 but continuing through 2020. Discussion: If tube B shows the greatest signs of rusting, and tube C and D shows little to no rusting, then both water and oxygen is needed for rusting … Experiment 14.2 To prevent rusting . Nail ‘1’ only. Gas bubbles appear around the magnesium ribbon. We used water & pickle juice in one container, and in the other we used vinegar & water. The water had changed due to the presence of rust. You are likely to start seeing results within 24 hours. Observe the corrosion of iron and investigate conditions related to corrosion. Aim: To investigate how different concentrations of sodium chloride affect the rate of corrosion on iron nails. Make sure you do not mix the nails up! 6. We are 6th graders doing a science fair project, on rusting nails. Pre-Lab Discussion. Report what you see in regard to the nails and any rust and compare the results for each solution. There isn't much research on the subject. This experiment received a the following result: 95%+.A Year 11 chemistry experiment which involves the reaction of nails in different types of liquid. Then compare the weights of the nail(and any rust)at the end of the experiment and compare it with the nail's original weight. Practical and results for a rusting experiment. No blue colour appears. Compare with the results of experiment (d). This experiment is a component of the Year 11 Chemistry course, and was assigned as a Practical Assessment Task. 3. Purpose. A stainless steel screw. A blue colour appears, mainly around the head and tip of the nail. Steel Nail Significant changes in the level of corrosion. Experiment to prove that air and water are necessary for rusting of iron Take three test tubes A, B and C and place one clean iron nail in each of them. Record your observations daily. Formation of Rust Expected Results: The tube(s) that show the greatest signs of rusting has the conditions necessary for rusting to take place. Add the weight of the rust to the nail it came from. Rusting should be faster in Hong Kong where the humidity is high. Extreme corrosion and rust e evident. Results: Results in Summary The following tables are a summary of the results of the two experiments: EXPERIMENT 1 DAY 1 DAY 7 DAY 14 NAIL IN WATER Some rust starting Nail rusting Nail rusting more NAIL COVERED WITH VASELINE No rust Small amounts of rust Some rust NAIL IN NO WATER No rust The other we used water & pickle juice in one container, and in the other we used water pickle.
