- Electrolysis
- AT THE POSITIVE ELECTRODE (called Anode)
- The negative ions are attracted. They lose electrons to the electrode and turn into the element.
- LOSING electrons is an oxidation reaction
- The negative ions are attracted. They lose electrons to the electrode and turn into the element.
- AT THE NEGATIVE ELECTRODE (called Cathode)
- The positive ions are attracted. They gain electrons from the electrode and turn into the element.
- Gaining electrons is a reduction reation
- The positive ions are attracted. They gain electrons from the electrode and turn into the element.
- = Passing electric current through an ionic liquid OR solution
- To split up the compound into elements that are useful...
- OPPOSITES ATTRACT
- POSITIVE IONS are attracted to the NEGATIVE ELECTRODE (cathode)
- NEGATIVE IONS are attracted to the POSITIVE ELECTRODE (anode)
- O I L R I G
- Oxidation Is Loss of electrons. Reduction Is Gain of electrons.
- PANIC
- Positive= Anode, Negative Is Cathode
- REMEMBER: Electrons move in a metal. Ions move in an ionic liquid or solution.
- AT THE POSITIVE ELECTRODE (called Anode)
