Extreme corrosion and rust e evident. The water had changed due to the presence of rust. Experiment involves the corrosion of nails in Coke, lemon juice, oil and water. You are likely to start seeing results within 24 hours. No blue colour appears. Gas bubbles appear around the magnesium ribbon. 2002. 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. Aluminium Foil Some changes were observed. 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 … 6. Practical and results for a rusting experiment. A discussion started in 2002 but continuing through 2020. We investigated the experiment over 14 days (2 weeks). Theory: Corrosion is the degradation of a metal due to chemical reactions between it and its surrounding environment (Bell, 2015). Rusting Nails student experiment and research. Pre-Lab Discussion. Rusting occurs in nail ‘1’, but not in nail ‘2’. Add the weight of the rust to the nail it came from. HELP! Steel Nail Significant changes in the level of corrosion. This experiment is a component of the Year 11 Chemistry course, and was assigned as a Practical Assessment Task. 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. We used water & pickle juice in one container, and in the other we used vinegar & water. Compare with the results of experiment (d). 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 website and its content is subject to our Terms and Conditions. Corrosion of Iron Experiment. Compare the results with those of experiment (b). Iron corrosion… Observe the corrosion of iron and investigate conditions related to corrosion. 3. Record your observations daily. This experiment received a the following result: 95%+.A Year 11 chemistry experiment which involves the reaction of nails in different types of liquid. Make sure you do not mix the nails up! Experiment 14.2 To prevent rusting . Formation of Rust Expected Results: The tube(s) that show the greatest signs of rusting has the conditions necessary for rusting to take place. A stainless steel screw. Nail ‘1’ only. 4. It is most commonly associated with rust, in particular the rusting of metals such as iron. 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 A blue colour appears, mainly around the head and tip of the nail. Q. In the test tube A pour some water and close its mouth with the help of a cork. The nails in tube “A” should remain rust-free, while the nails in tube “B” should begin to rust. Aim: To investigate how different concentrations of sodium chloride affect the rate of corrosion on iron nails. Over the next week, observe your experiment and record your observations. We are 6th graders doing a science fair project, on rusting nails. 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. Rusting should be faster in Hong Kong where the humidity is high. Corrosion is an oxidation-reduction (redox) reaction in which a free metal is oxidized, or “corroded,” by some oxidizing agent. The aluminium foil got lighter in color and started to fade, disintegrate and fall apart in a few places. Purpose. A galvanized nail or screw has a zinc (obviously) finish.
