Molten Ionic Compound
Chemistry: AQA GCSE Higher, topic 4.4.2
Test yourself on Molten Ionic Compound
Which ions are attracted to which electrode?
During electrolysis of molten copper oxide, copper metal forms at the cathode. What does this show about the charge on copper ions (Cu2+)?
Why must a solid ionic compound be heated until molten before it can be electrolysed?
During electrolysis of a molten ionic compound, why do the metal and the non-metal form at different electrodes?
Oxide ions move to the anode during electrolysis of molten copper oxide. What does this show about their charge?
