So, since this develops a negative charge, let's see what happens with the portion that's immersed into our liquid. Well, we said some of the sodium molecules will be moving around, and since they are positively charged, they will be attracted to this negatively charged electrode. Likewise, these chloride atoms are negatively charged, so they will be attracted to this positively charged electrode. So we'll have a separation of sodium and chloride in our liquid. Now, what happens when our sodium positively charged ion hits this negatively charged electron? Well, some of the electrons will transfer into our sodium molecule, and that means our sodium will be reduced.
