Revision Schedule grade 10 chemistry

 

10-Day Revision Plan

Chemical Reactions & Equations + Acids, Bases and Salts

---

Day 1 — Chemical Equations Basics

• Writing and balancing chemical equations (hit-and-trial method)
• Word equations → symbol equations
• Types of reactions: Combination & Decomposition
  • Sub-types of decomposition: thermal, electrolytic, photolytic
• Practice: Balance 15–20 equations from NCERT

Day 2 — More Reaction Types

• Displacement and Double Displacement reactions
• Precipitation reactions (identify precipitate formation)
• Oxidation & Reduction — definitions in terms of gain/loss of oxygen and hydrogen
• Redox reactions — identify oxidised/reduced species in given equations
• Practice: Identify reaction type for 20 mixed equations

Day 3 — Everyday Applications

• Effects of oxidation in daily life: Corrosion and Rancidity
• Ways to prevent rancidity (antioxidants, airtight containers, refrigeration, nitrogen flushing)
• Quick revise Day 1 & 2 concepts (10 min flash recall, no notes)
• Solve 5 previous-year/HOTS questions

Day 4 — Full Revision: Chapter 1

• Complete NCERT in-text + end-of-chapter questions
• Make a one-page equation/keyword cheat sheet
• Self-test: 15 MCQs + 5 short-answer questions (timed, 30 min)

Day 5 — Acids and Bases: Properties

• Chemical properties of acids and bases
• Reaction of acids/bases with metals (H₂ gas test)
• Reaction with metal carbonates/bicarbonates (CO₂ test)
• Reaction of acids with bases (neutralization)
• Natural, synthetic, and olfactory indicators (litmus, turmeric, onion/vanilla)

Day 6 — pH Concept

• pH scale (0–14), pH paper vs universal indicator
• Relation between H⁺ ion concentration and pH
• Importance of pH in everyday life:
  • Human body (stomach acid, tooth decay)
  • Plants and animals (soil pH, aquatic life)
  • Digestion (antacids)
• Practice pH-based numericals/diagram questions

Day 7 — Salts (Part 1)

• Family of salts, pH of salt solutions (acidic/basic/neutral salt)
• Common salt (NaCl) — preparation & uses
• Chlor-alkali process → NaOH, Cl₂, H₂ and their uses
• Bleaching powder — preparation, formula (CaOCl₂), uses

Day 8 — Salts (Part 2)

• Baking soda (NaHCO₃) — preparation, uses, reaction on heating
• Washing soda (Na₂CO₃·10H₂O) — preparation from baking soda, uses
• Plaster of Paris (CaSO₄·½H₂O) — preparation, setting reaction, uses
• Water of crystallization — concept + examples (gypsum, blue vitriol)
• Revise Day 5–7 with a self-made table (salt | formula | prep | uses)

Day 9 — Full Revision: Both Chapters

• Redo all equations from both chapters without looking (write from memory)
• Diagram practice: activity setups (e.g., zinc + acid, rusting experiment)
• Solve previous year board questions (both chapters mixed)
• List down formulas/definitions still shaky — mark for Day 10

Day 10 — Mock Test + Final Touch-Up

• Take a full mock test (1 hour): mix of MCQs, short answer, long answer, HOTS
• Evaluate and identify weak spots
• Rapid-fire revision of:
  • All reaction types with examples
  • All salt formulas and uses
  • pH values of common substances
• Final cheat-sheet read-through (both chapters, 20–30 min)

Daily Tips

• Spend the last 10 minutes of each day writing 5 equations from memory.
• Keep a single running list of "confusing points" — review it every 2 days.
• Use active recall (self-quiz) over passive re-reading wherever possible.
