Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Oxidation and Reduction (Redox Reactions), 2. Oxidation Number and Rules, 3. Balancing Redox Reactions.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Electro Chemistry after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Oxidation: loss of electrons
  • Reduction: gain of electrons
  • Redox reactions involve simultaneous oxidation and reduction
  • Oxidation number is a bookkeeping tool for electron transfer
  • Rules help assign oxidation numbers systematically
  • Sum of oxidation numbers = 0 in neutral compounds, equals charge in ions
  • Two methods: oxidation number and ion-electron
  • Ion-electron method is more systematic for complex reactions
  • In acidic medium, use H⁺ and H₂O; in basic, use OH⁻ and H₂O

Common Mistakes to Avoid

Oxidation always means adding oxygen, and reduction always means removing oxygen.

Oxidation number and charge are the same thing.

In a galvanic cell, electrons flow from cathode to anode.

Memory Tips

Oxidation is loss, reduction is gain (of electrons)

Anode is where oxidation occurs, cathode is where reduction occurs

Electrons flow from anode to cathode in external circuit

Rules for assigning oxidation numbers
