Electrochemical Cell Notation

🔋 Electrochemical Cell Notation Rescue Plan

🧾 Standard Cell Notation:
Anode | Anode Solution (conc.) || Cathode Solution (conc.) | Cathode

✨ Single line = phase boundary. Double line = salt bridge. Left side = oxidation (anode).

🔥 Key Rules to Follow

• Always write the anode (oxidation) on the left
• Use | between different phases (solid | aqueous)
• Use || to indicate the salt bridge
• Inert electrodes (Pt or C) are used if no solid is present

🧠 Sample Notation Breakdown

Cell: Zn(s) | Zn²⁺(1 M) || Cu²⁺(1 M) | Cu(s)
Which is the anode?

⚡ One Line Hack:

LEO (Loss of electrons = Oxidation) always happens at the anode. Anode always goes on the left.

⚙️ Build-A-Cell

You have Fe³⁺/Fe²⁺ and Ag⁺/Ag. Write the standard notation using a Pt electrode for Fe.

✏️ Cell Notation = Anode | Solution || Solution | Cathode. Keep the redox order straight!
