COCA removes RUST BUT it is not a rust preventative! Metal corrosion, redox reactions.
Coca-Cola, or any acidic beverage, can remove rust. I'll explain what metal corrosion is, how rust forms, and how to protect yourself from iron corrosion.
Then, I'll demonstrate that cola can remove rust... but:
It's not a rust remover! Be careful: acids attack metals!
This video covers the topic of metal corrosion and redox reactions in high school, for students in the first and final years of general and STI2D tracks.
A redox reaction is provided at the end of the video and must be balanced.
