What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited
The first answer to the equation above is quite right, or it may be that a layer of calcium carbonate is attached to the surface of the electrode, which prevents the electrode from conducting and leads to an increase in resistance
