HeyIHaveAProblem Posted March 1, 2005 Report Posted March 1, 2005 Hi, I'm am currently doing a science experiment in my High School chemistry class. The title of my experiment is, "The effect of the treatment of iron on the amount of rust produced." My problem is the treatment of iron part. So far, I have these three treatments: Water (H20), saltwater, and vegetable oil. But my teacher says that these three treatments have nothing to do with each other... so therefore, I need to come up with different treatments that are similar. Any help? I've tried looking it up online, but all i'm coming up with is rust prevention products. Any help would be greatly appreciated. Quote
bumab Posted March 1, 2005 Report Posted March 1, 2005 Maybe different strength acids and bases? That way it's all centered around the water (at 7.0) Quote

You say you have an experiment. Is this experiment supposed to test some hypothesis? What is that hypothesis? Are you trying to demonstrate what causes rust and how to prevent it? A little more explanation on what you are trying to accomplish will help us to help you. Quote

A little more explanation on what you are trying to accomplish will help us to help you. I am not really trying to prove anything, I just thought it would be fun and easy experiment to conduct. We can do anything that has to do with science as long as the difficulty is up to our level. My hypothesis if I use saltwater, then the amount of rust produced would be the greatest. However... like I said earlier, I cannot use this treatment because the treatments have nothing to do with each other. The hard part is coming up with three (or more) different types of treatments that are similar (such as 3 different types of oils). Also, vegetable oil cannot be used as a treatment because it would completely prevent rust (also because I already know the results beforehand). Also, before you say anything. This experiment is the easiest that I could find that is "up to my level". yes, i'm lazy Quote

Fishteacher73 Posted March 2, 2005 Report Posted March 2, 2005 i could see two other ways, instead of the "rust inducing" medium, try different types of iron alloys. Or you could paint the ingots with various types of paint/ sealant/ etc. With this would only use one thing to cause the rusting. Quote
C1ay Posted March 2, 2005 Report Posted March 2, 2005 My hypothesis if I use saltwater, then the amount of rust produced would be the greatest. Could you then use different strengths of saltwater to test your hypothesis, maybe one with no salt, one with moderate salt and one with a liberal portion of salt? Quote
pgrmdave Posted March 2, 2005 Report Posted March 2, 2005 I think it would be best done with four peices of iron - one peice of Iron left alone with no solution on it - the controlone with distilled water on itone with a very small amountone with a moderate amountone with as much salt as will disolve in the water Then you test each for rust, to see which has the most.

Fishteacher73 Posted March 2, 2005 Report Posted March 2, 2005 When you say salt water do you mean water with sodium chloride desolved into it or a synthetic(or real for that matter) sea water (They are increadibly different mixtures). Quote
HeyIHaveAProblem Posted March 3, 2005 Author Report Posted March 3, 2005 Ok, thank you all. I'm going to do the amount of saltwater on the amount of rust. Quote
