Electrolysis Flashcards
what current must be used during electrolysis
direct
what happens when a voltage is applied across the electrolyte
positively charged ions move towards the cathode negatively charged ions move towards the Anode
what happens when ionic compounds are dissolved in water
charged ions become free to move the liquid solution will conduct electricity
what does Panic stand for
positive is anode negative is cathode
what does oil rig stand for
oxidation is loss of electrons reduction is gain of electrons
What is formed at the anode
Oxygen unless you have a group 7 present
what properties must an electrode have
be able to conduct electricity and be unreactive
what is formed at the cathode
hydrogen and less copper Gold silver or platinum is present
where does the nonmetal form
anode
where does the metal form
cathode
what forms at the positive electrode
 bubbles
what forms at the negative electrode
Brown solid
