Corrosion of metal iron. Which of the statement are correct? Three answers.
The reaction starts at anode, which iron oxidizes to form iron ion and electrons.
The reaction starts at cathode, which oxygen and water reacts with electrons to form hydroxide ions
After anode, the electrons move to the cathode. Oxygen and water reacts with electrons to form hydroxide ions
The iron ion and hydroxide ion react to form rust.
