How to Study Electrochemistry

A structured approach to studying Electrochemistry for KEAM Chemistry.

Study Plan for Electrochemistry

1

Day 1–2: Learn the Theory

Study the chapter thoroughly. Note down definitions, formulas, and key concepts.

2

Day 3: Practice Problems

Solve practice questions and previous year KEAM problems. There are 271 questions available for this chapter.

3

Day 4: Revise & Test

Revise key formulas and concepts without looking at notes. Take a practice quiz to test your understanding.

What to Focus On

  • Electrochemical cells have two half-cells connected by salt bridge
  • Anode: oxidation occurs (negative terminal in galvanic cell)
  • Cathode: reduction occurs (positive terminal in galvanic cell)

  • Standard conditions: 298K, 1 atm pressure, 1M concentration
  • SHE is reference electrode with E° = 0.00V
  • Positive E° means easier reduction than H⁺/H₂

  • Higher E° = stronger oxidizing agent
  • Lower E° = stronger reducing agent
  • Nernst equation shows concentration dependence

Common Mistakes to Avoid

In a galvanic cell, the anode is positive and cathode is negative because current flows from positive to negative

Cell potential (EMF) can be calculated as Eanode - Ecathode

In electrolytic cells, the anode is positive and cathode is negative, opposite to galvanic cells
