Showing the corrosion of metals when placed in acid

[val1ant]

Homework Statement

for a science experiment i am required to write relevant chemical equations to reactions that have occurred. I am having trouble showing the corrosion of iron, aluminum and copper in acetic acid and citric acid.

Homework Equations

heres what i have so far:

Fe + 2 CH3COOH → (CH3COO)2 Fe + H2

i think this is the reaction that iron and acetic acid undergo, but not too sure.

The Attempt at a Solution

im lost as i don't know what happens to iron in acetic acid
and also what catalyses this reaction?
thanks in advance for you help

Fe + 2 CH3COOH → (CH3COO)2 Fe + H2

This is correct, although I prefer to write iron acetate as Fe(CH₃COO)₂. But it is just a personal thing.
