Iron and Steel Corrode to Make Rust Flashcards
1
Q
What does iron do easily?
A
Corrode (rust)
2
Q
When does rusting only happen?
A
When the irons in contact with both oxygen and water
3
Q
What is the chemical reaction that takes place when iron corrodes?
A
An oxidation reaction - gains oxygen to form iron(III) oxide
4
Q
Water then becomes loosely bonded to the iron(III) oxide and the result is…
A
Hydrated iron(III) oxide - rust
5
Q
Word equation for reaction:
A
Iron + oxygen + water —> hydrated iron(III) oxide (rust)
