Common mistake
Misunderstanding Ion Movement
Students often confuse the movement of ions during electrolysis, thinking that positive ions move to the anode instead of the cathode.
Remember that positive ions are attracted to the negative electrode (cathode) where they gain electrons, while negative ions move to the positive electrode (anode) to lose electrons.
