- Finding difficulties in memorizing things? Let us learn it in some easy ways.
For remembering what is oxidation and reduction
Just remember Leo and GER:-
-Loss of Electrons-Oxidation
-Gain of Electrons-Reduction
For remembering the polarity of electrodes in a voltaic cell.
Just remember VAN:-
Voltaic (cell)-Anode Negative
Now as you know voltaic cell has only two electrode, the remaining electrode i.e. Cathode is positive- hitting-two nails with one hammer!
To remember what reaction happens at which electrode:-
Anode for oxidation
Remembering the electron flow in an Electrochemical cell
Just remember FAT CAT
Flow Anode to Cathode
