Transcript of Which liquid will rust a nail the fastest- coke, apple juice, orange juice, water, or vinegar?

Which liquid will rust a nail the fastest? Coke, apple juice, orange juice, vinegar, or water! By Alex Muchinsky What do you think? Topic! For For my science project I decided I wanted to study physical sceince! Problem! Which liquid will rust a nail the fastest- water, coke, apple juice, orange juice, or vinegar? Hypothesis If I test water, orange juice, coke, apple juice, and vinegar to see what liquid will rust the fastest, then I think the orange juice will rust the fastest, because it is the most acidic and carries the most acid. Variables My independent variable is the nail.

My dependent variable is the difference of the nail, the rusting done to the nail.

I will measure my dependent variable by recording the results each day.

The control variables in my experiment are the kind of liquids, the amount in each jar, cup, or bottle.

Research! Source 1
bibliographic information:
HowStuffWorks "How does rust work?"

I learned that rust is the common name for a compound called iron oxide.

I also learned that iron or steel rusting is an example of what’s called corrosion.

In addition I learned that 3 things are required for iron to turn to iron oxide- iron, water, and oxygen.
Source 2
Bibliographic information What is Rust? - wiseGEEK

I learned that rust is scientifically proven called oxidation.

I also learned that rusted aluminum is called aluminum oxide.

In addition I learned that when oxygen comes in contact with certain and water hit the medal it weakens the bonds of medal, rusting it!

Source 3

Bibliographic information: Encyclopedia Britannica

I learned that to a pure scientist corrosion reactions should form a division of chemical kinetics.

I also learned that oxidation is very fast at first but then slows down.

In addition I learned that rusting happens when heat (sun) and water affect iron and rusts it.

The apple juice was weird because when you opened it up it was like you were opening up a new soda, because it was pressurized. It was carbonated, I have no idea why that happened. I was surprised when the Orange Juice and Coke did not rust a nail the fastest and the Apple Juice did. The Apple Juice is juice which is acidic so that explains that but the Orange Juice is juice also and is most likely more acidic than Apple Juice. Coke is soda, not juice so that’s also very acidic but it did not rust the nail like that Apple Juice.

The coke did not turn out to have any rust but did actually turn out to turn the color black! I think it was because of the cokes own color, I thought either the Coke or OJ would rust the nail fastest because usually the most acidic drinks rust metal (or iron) the fastest, something might have happened. The black might have been rust, I don’t know. The Cokes own color might have affected it or we used a weird type of metal.
Orange Juice! Day 1
See- looks new, like a regular nail that you just bought and has not been affected

My hypothesis was wrong, I thought it was the Orange Juice but I guess it wasn’t. You’d think it would have just a little bit of rust on it. I didn’t have one bit! It looked good as new! It was not affected at all! The only thing you could really say about it was that it was sticky from the juice.

The vinegar had no difference whatsoever, it was all the same. Vinegar does not smell very good. It had no rust at all. Which is no surprise, I had a feeling that it was not going to rust.

I was surprised when I found out that the Water rusted the nail the fastest, usually you would think it would be the most acidic! Which, by the way is not the water. The water is the most common liquid that rusts the nail the fastest though. Anyway, these results surprised me.
Data Measurements I will measure my data by checking the nail everday and writing down what I see. Data Measurements Paragraph 1! In my experiment I tested 5 different liquids to see which one would rust a nail the fastest. Those liquids where water, apple juice, orange juice, vinegar, and coke. My hypothesis was the orange juice would rust the fastest because it is the most acidic. I was wrong; the one that rusted the fastest was actually water. That was very unexpected, water was the one that I least suspected would rust the fastest. The coke was my second guess of what would rust the fastest. This liquid is also very acidic. These liquids (orange juice and coke) are acidic because orange juice is juice, and coke is soda. These kinds of drinks are usually very acidic. The coke nail actually turned black. The apple juice was very carbonated and pressurized.

Paragraph 2! In my research I learned a couple other words or examples of rusting. I also learned a little bit more about rust and some specific names for it. Another word for rust is oxidation. Rust is also commonly called corrosion. I learned that 3 things are needed for rusting to occur iron/ metal, heat (sun), and oxygen. I also learned that when aluminum is rusted it then turns to aluminum oxide! Same with iron it just turns to iron oxide not aluminum oxide! When rust, corrosion, oxidation- whatever you want to call it! When it occurs it weakens or bends the metal/ iron. Some pure scientists would explain this as a division of chemical kinetics. Paragraph 3! I would like to again the exact same except testing different sodas. Such as: Fanta, Fresca, Sprite, Orange Crush, and Dr. Pepper. I would like to see which one would rust the fastest but not only that. I would also like to test and see which one is the most acidic. As you can see in my hypothesis I said that I thought that the orange juice would rust the nail the fastest because it was the most acidic. Well Coke was my second guess because just as orange juice because it is a juice. Juices are very acidic. So are sodas, Coke is a soda. So are all of the examples I gave earlier. The most acidic will most likely rust a nail the fastest. This experiment could help you have a better understanding of acidic sodas and drinks. Less healthy drinks tend to be acidic. This could help you also with health in life. This could also help you with rusting troubles too. Pictures! Thats my science project! The end!
