My project is the the effect of the material of hardware on corrosion through acid rain. I bought four different types of metals/alloys in the form of either a nail or a screw (some of the metals/alloys aren't used to make nails so I had to buy screws or vice versa). For my project I'm going to make a solution of vinegar water, dip the hardware in the solution, and then leave the hardware out. After it is dry (6 hours), I'm going to take the mass of the nails and repeat 4 or 5 times.
I have 2 problems. I'm not sure whether this is the process of oxidation or corrosion, which is actually quite a big problem because it's the main concept of my experiment. I've had it explained to me by a cousin of mine and he said that oxidation is a broad topic and corrosion is a type of oxidation which is always destructive. Is this accurate? So my title could say oxidation, but corrosion is more specific? Just to clarify, I'm NOT using iron as a metal, which would change things, correct? Then everything would be corrosion except for that which would be rust, which IS a type of oxidation but NOT a type of corrosion?
Second, should the hardware be gaining or loosing mass? I'm almost sure it would be losing mass, but if for some reason the answer to my above question is oxidation and not corrosion, then I have no idea what it would be doing.
I was previously having a really difficult time understanding this because I was under the impression that oxidation and rust were synonymous, but now I know that rust just refers to when iron is oxidized (iron oxide) and that there are different types of oxidation. Basically, I think I understand everything now but I just want to make sure that everything I think is actually correct.
Please answer, I have less than a week until my project is due!
And thanks in advance!
