So first, let's look at our electrolytic cell. So in this cell, we have a battery, a voltage cell that powers our reaction, and it powers it by sending electrons this way. So that means this electrode will collect these electrons, making it negatively charged. At the same time, this electrode will lose electrons, making this guy positively charged, because electrons will want to flow from this guy to this guy. So let's look at our solution. Within our solution, we have a bunch of sodium ions dissolved and chloride ions dissolved.
