I did an experiment where i put iron nail with zinc metal wrapped around it in agar solution.

the solution turned pink.
I have to find the
anode:

anode reaction:

cathode (remember, a metal can be an inactive electrode):

cathode reaction (there arenít any metal ions present, so the metal does not get reduced. Something else does. What is it?) :

the notes in the () are notes my teacher wrote.

That means the anode is zinc. the cathode iron. The cathode reaction is oxygen because it's getting reduced. What is the anode reaction?
