Here’s where it gets weird. Iron reacts with water and oxygen to form rust. Rust is not iron—it’s iron oxide.
And guess what? Rust does dissolve a tiny bit in water. It’s like the iron turns into a microscopic powder that floats away.
That’s why old pipes turn your bathwater brown. You’re not drinking iron—you’re sipping rusty rust tea.
Fun Fact: The Iron Titanic
The Titanic is slowly dissolving on the ocean floor. Cold, deep water with low oxygen makes it rust slowly. But bacteria are actually eating the iron.
They poop rust, which then dissolves. Yes, the ocean is digesting a famous ship.
