Mnemonics: Electrochemistry | Chemistry Class 12 - NEET PDF Download

Introduction

Prepare to unlock the mysteries of electrochemistry with these easy-to-remember mnemonics that will simplify concepts such as cell potentials, electrodes, and redox reactions.

Reactivity Series

Mnemonic: "King's Sister Came Marching And Zipped Into Tiny Little Hut, Caught Stealing Gold."

• King's : Potassium (K)
• Sister : Sodium (Na)
• Came : Calcium (Ca)
• Marching : Magnesium (Mg)
• And : Aluminium (Al)
• Zipped : Zinc (Zn)
• Into : Iron (Fe)
• Tiny: Tin (Sn)
• Little: Lead (Pb)
• Hut: Hydrogen (H)
• Caught: Copper (Cu)
• Stealing: Silver (Ag)
• Gold: Gold (Au)
  

Oxidation and Reduction

Mnemonic: "LEO the LION says GER."

• LEO: Loss of Electrons = Oxidation
• LION: Loss Increases Oxidation Number
• GER: Gain of Electrons = Reduction

Cation 

Mnemonic: "Cats Are Pawsitive."

• Cats : Cation
• Pawsitive.: Indicates the positive charge of the cation

Cations are positively charged ions that move towards the cathode during electrolysis.

Anion

Mnemonic: "AN ION."

• AN : Anion- A Negative
• ION:  Ion

Anions are negatively charged ions that move towards the anode during electrolysis.

Reduction in Electrochemical Cell

Mnemonic: "RED CAT."

• RED: Reduction
• CAT: Cathode

Reduction occurs at the cathode in an electrochemical cell. 

Oxidation in Electrochemical Cell

Mnemonic: "AN OX."

• AN: Anode
• OX: Oxidation

Oxidation occurs at the anode in an electrochemical cell.

Flow of Electron in Electrochemical Cells

Mnemonic: "FAT CAT."

• FAT: Electrons flow From Anode
• CAT: Cathode

In an electrochemical cell, electrons flow from the anode to the cathode.

In electrochemistry, mnemonics like these simplify the understanding and memorization of key concepts, from the reactivity series to the behavior of electrons, making complex topics more accessible and easier to recall.
