Question

In basic terms, Why does water make iron rust faster than air?

In: Chemistry

Answer 1

Because water has more water than air does (yes, that’s a bit obvious), so a reaction that happens when water interacts with iron and oxygen (rusting) happens faster with more water. The only real reason iron in air rusts is because the air has *some* water to it.

(and even faster with ions, like salt, in the water)
