Module 6. Materials & hardware

In corrosion, the electrode that loses electrons is

  • the cathode.
  • either the cathode or the anode depending upon the electrolyte.
  • the anode.

android811 asking:

I don't understand.
Cathode is positive and electrons are negative. How can electrons ever be attracted to anode?

I agree that the answer is incorrect but the cathode is negative not positive. CNAP - Cathode Negative Anode Positive.

Ok thanks, I just remember cations are positively charged. This is going to be tough to remember!

Anode - The electrode where galvanic reaction(s) generate electrons - negative ions are discharged and positive ions are formed. Corrosion occurs at the anode.
