Step 1: Balanced equation and the number of electrons

When writing a cell notation, we use the following format – “as easy as ABC Recall the mnemonics LEO GER.

Lose               Gain

Electron         Electrons

Oxidation       Reduction

lose electrons → oxidation → anode

gain electrons → reduction → cathode We’re going to write the overall balanced reaction equation using the following sub-steps:

Sub-step 1: Write the anode reaction.

Sub-step 2: Write the cathode reaction.

Sub-step 3: Balanced anode and cathode reactions.

Sub-step 4: Get the overall reaction. ###### Problem Details
