Help! I'm getting confused about this part. Many of my references say the potato contains phoshoric acid which causes the chemical rections to occur at each of the electrodes. The copper electrode electrons and acid form hydrogen gas,then the phoshoric acid desolve the Zinc giving positive IONs from the electons that stay on the electrode. These Zn++ migrate in the electrolytic solution Acid Juices in the potato then if the Zinc and copper electrodes are connected a electric current flows. But, I read your achived message ID# 943757681.Ch and ID#916286185.PH, these say it's not the Acid in the potato, and state the Salts in the potato are the source of the ions, (Sodium +, and Chlorine -). In those references the Na+ and Cl- are what charge the electrodes and the elctrons are the carriers for the electricity. Can you please help me reconcile this information?
