Electrolysis is passing electricity through a solution to break it up. Cations go towards the cathode which is negatively charged SO cations are POSITIVE and usually metals. Anions go towards the anode which is positively charged SO anions are NEGATIVELY charged and usually non metals.
At Cathode:
Cu2+ + 2e- ----> Cu (half equation)
Cu - 2e- ----> Cu2+
Oxidation is the loss of electrons
Reduction is the gain of electrons
Least reactive - 2H+ + 2e- ---> H2
At Anode:
Get oxygen unless you have a halogen
Cl- - 2e- ----> CL2
At the cathode the substance…
