Conclusion

For my conclusion I had finally got my answer. My hypothesis was correct since the nail in the vinegar hadn't even rusted at all, the nail in the sprite had completely rusted all over and finally the nail in the soda water had white patches which I found out is soda powder and had the bit of rust on at the bottom which seemed to be different to the rust on the nail in sprite, it looked like it had rusted for years since it was very red. but the other parts remained clean as if they were new. I then also discovered why the sprite had rusted faster then the4 soda water, it was because of the air bubbles that had oxegen inside them. What actually made nails rust actually the electrons inside the liquids which can be enhanced when it comes in contact with oxegen. I could have improved the experiment by adding a few more alternatives and testing them. So overall it left with soda water having the pH of 8 having the 2nd most rust, but greater intensity of rust. The nail with the most rust was the nail in sprite with the pH of 5 and the nail with no rust at all was the one in vinegar with the pH of 2.
