1. The problem statement, all variables and given/known data In Galvanic Corrosion, does the cathode gain mass, while the anode loses mass? 2. Relevant equations 3. The attempt at a solution The anode loses electrons to the cathode through the electrode. But i am not sure whether the cathode would gain mass or not. If so, when the anode lose 2g, does that mean the cathode would gain 2g as well?
