Now, I want to talk about a different type of electrochemical cell called the concentration cell. Now, in this cell, we also have two half cells or two beakers. We also have a salt bridge and a conductor with a bolt meter. The only difference is that now we have the same exact electrode. So this electrode might be composed of some metal x, and this electrode is also composed of that same metal. So now we have the same type of reaction occurring in Baker One and Baker Two.
