We see the positive blue copper ions move to the negative electrode and the negative yellow chromate ions move to the positive electrode. Chemistry - Reactions - Learning Points. Ions have a positive or a negative charge. Positive copper ions are attracted to a negative carbon electrode; negative chromate ions are attracted to a positive carbon electrode. Some ions have distinctive colours; these are usually the ions of the transition metals. A Twig Experiment Film. Let students experience real experiments in lab conditions anywhere, from setup, method all the way through to analysis and real-world application.\n
