ICSE Class 9 Chemistry Books: what is inside each chapter

Three numbers carry this section. A section is one of the book’s own main headings — sub-headings are not counted. A practice question is a numbered item under an exercise heading. Pages is the chapter’s length in the PDF.

Chapter 1: The Language of Chemistry (Chemistry)

Every formula a student writes rests on the ideas in this chapter. It starts with chemical symbols and the formula, then valency and radicals, and puts them to work in writing chemical formulae and naming certain compounds. The later sections calculate valency from a formula, turn it into a chemical equation, and move into relative atomic mass, relative molecular mass, percentage composition and empirical formula.

• 1.2 Chemical Symbols
• 1.3 Formula
• 1.4 Valency
• 1.5 Radicals
• 1.6 Writing Chemical Formulae
• 1.7 Naming Certain Compounds

and 6 more

Exercise 1(C) sets 17 questions.

Chapter 2: Chemical Changes and Reactions (Chemistry)

A chemical reaction is defined up front, with the characteristics that mark one as having taken place. A negative catalyst earns a mention among them. The chapter then runs the reaction types the sections name — combination, thermal dissociation with experiments, displacement with experiments, and the uses of neutralisation — followed by photochemical and electrochemical reactions.

• Chemical Reaction
• (b) Negative catalyst
• Characteristics of Chemical Reactions
• Excercise 2(A)
• In combination reactions
• Experiments : to show thermal dissociation

and 7 more

Chapter 3: Water (Chemistry)

The treatment of water starts from its physical properties. The chapter covers water as a universal solvent and solutions as mixtures of solids in water, then saturated solutions, concentration and solubility. From there it moves to crystals and crystallization, hydrated and anhydrous substances, and drying and dehydrating agents. Soft and hard water come next, with the types of hardness — temporary and permanent — separated out.

• 3.2 Physical Properties of Water
• 3.3 Water as Universal Solvent
• 3.4 Solutions as Mixtures of Solids in Water
• 3.5 Saturated Solution
• 3.6 Concentration of a Solution
• 3.7 Solubility

and 6 more

Chapter 4: Atomic Structure and Chemical Bonding (Chemistry)

The atom is built from its parts here. The chapter defines the atom, names its constituents and follows the discovery of the nucleus, Bohr’s atomic model and the discovery of neutrons. Atomic number and the Bohr-Bury scheme of electron distribution lead to valence electrons and the reason for an atom’s chemical activity. Isotopes and the covalent (molecular) bond sit alongside them.

• 4.2 Definition of an Atom
• 4.3 Constituents of an Atom
• 4.5 Discovery of Nucleus
• 4.6 Bohr’s Atomic Model
• 4.7 Discovery of Neutrons
• 4.8 Atom — Its Structure

and 6 more

Chapter 5: The Periodic Table (Chemistry)

The drive to classify elements came before any workable system. The chapter walks the historical attempts — Dobereiner’s triads, Newland’s law of octaves, Mendeleev’s periodic table and its law, with the defects each carried. Atomic number then becomes the basis for the modern periodic law and the long form of the periodic table, with groups, periods and the types of elements. The study of specific groups and the uses of the periodic table follow.

• Reasons for Classification of Elements
• Dobereiner’s Triads
• Newland’s Law of Octaves
• Mendeleev’s Periodic Table
• Mendeleev’s Periodic Law
• Essential features of Mendeleev’s periodic table

and 38 more

Chapter 6: Study of the First Element Hydrogen (Chemistry)

Hydrogen is positioned before it is studied. The chapter weighs hydrogen’s position in the periodic table, setting its similarities to alkali metals against its similarities to halogens. Discovery, occurrence and preparation of hydrogen follow. The later sections take up the manufacture and uses of hydrogen, then oxidation and reduction.

• 6.1 Position of Hydrogen in Periodic Table
• 6.2 Similarities Between Hydrogen and Alkali Metals
• 6.3 Similarities Between Hydrogen and Halogens
• 6.4 Discovery
• 6.5 Occurrence
• 6.6 Preparation of Hydrogen

and 3 more

Chapter 7: Study of Gas Laws (Chemistry)

Gases behave predictably, and this chapter names the relationships. It opens with the behaviour and characteristic properties of gases and molecular motion, then the gas laws — the pressure and volume relationship and the temperature-volume relationship. The absolute or Kelvin scale of temperature follows, with Celsius-Kelvin conversion, the gas equation and standard temperature and pressure. The effect of moisture on pressure is treated in a section of its own.

• 7.2 Behaviour and Characteristic Properties of Gases
• 7.3 Molecular Motion: Relationship of Temperature, Pressure and Volume
• 7.4 The Gas Laws
• 7.5 Pressure and Volume Relationship in Gases
• 7.6 Temperature-Volume Relationship in Gases
• 7.8 Absolute or Kelvin Scale of Temperature

and 4 more

Chapter 8: Atmospheric Pollution (Chemistry)

Air pollution is the starting point, and each named consequence gets its own section. The chapter covers acid rain, global warming and ozone in that order.

• 8.2 Air Pollution
• 8.3 Acid Rain
• 8.4 Global Warming
• 8.5 Ozone

The single exercise, Exercise 8, sets 25 questions.

Chapter 10: Atmospheric Pollution (Rachna Sagar)

The Rachna Sagar chapter carries the same title and then widens its sweep. Atmospheric pollution is the lead section. Water and water pollution follow it.

• Atmospheric Pollution
• (Appendix)
• Water
• Water Pollution

Important Questions sets 10 questions, with 3 answers given.

Chapter 1: Matter and Its Composition Law of Conservation of Mass (Simplified)

Matter and its composition sit at the centre of this chapter, introduced through chemistry and modern chemistry. The kinetic theory of matter explains solids, liquids and gases, and the change of state on that basis. The law of conservation of mass gets its statement, explanation and two experiments.

• Matter and Its Composition – law of conservation of mass
• A. Introduction – to Chemistry
• Modern Chemistry
• Matter and Its Composition
• I. Main Postulates of – Kinetic Theory of Matter – are summarized below
• II. Solids – Inter-particle space & Inter-particle attraction

and 8 more

Additional Questions runs to 40 numbered questions.

Chapter 3: Elements Compounds and Mixtures (Simplified)

All four sections here are separation methods, grouped by what is being separated. Solid-liquid mixtures come first, then liquid-liquid, liquid-gas and gas-gas mixtures.

• Separation of solid-liquid mixtures (Homogeneous mixtures).
• Separation of liquid-liquid mixtures
• Separation of liquid-gas mixtures.
• Separation of gas-gas mixtures.

The practice here is one set of 8 questions under Important Questions.

Chapter 6: Water Water Pollution (Simplified)

Water fills most of this chapter before pollution takes over. It opens with the water cycle, water as a compound and not an element, natural and treated water, and the effects of pressure and solutes on boiling and freezing points. From there it moves through water as a universal solvent, solutions from dilute to saturated, solubility and solubility curves, then crystals and drying agents. The chapter then turns to pollution, pollutants, water pollution and its treatment.

• Water
• A. Introduction
• The Water Cycle
• Water – Is Considered a Compound and not an element.
• Natural & Treated Water
• Boiling and Freezing Points of Water Are Affected by – Change in Pressure and by Addition of Solutes

and 41 more

Additional Questions is the larger set, 65 questions on top of the 15 in Questions.

Chapter 9: Study of the First Element Hydrogen (Simplified)

Placement in the periodic table comes first, and the chapter names hydrogen’s dual nature and resultant position before discovery and occurrence. The laboratory preparation follows — apparatus, reactants, and the collection and purification of hydrogen. It then moves to the industrial methods: the Bosch process, electrolysis of water or brine, and hydrogen from natural gas or calcium hydride.

• Study of the First Element – Hydrogen
• A. Position of the Non-Metal – Hydrogen in the periodic table
• Position of Hydrogen – in the Periodic Table
• Dual Nature of Hydrogen
• Resultant Position of Hydrogen
• Discovery

and 10 more

Additional Questions carries 46 questions, with 26 in Questions before it.

How to revise Class 9 Chemistry chapter by chapter

1. The Language of Chemistry — symbols, valency and formulae are the working language every later chapter assumes, so it belongs first.
2. Atomic Structure and Chemical Bonding — its Bohr-Bury scheme and valence electrons show where the valency of Chapter 1 comes from.
3. The Periodic Table — hydrogen’s first section is its position in the periodic table, so the table comes before the element. It also carries the longest section list on this page, at 44 sections, so give it room.
4. Study of the First Element Hydrogen — builds on that position and carries oxidation and reduction with it.
5. Study of Gas Laws — pressure, volume, temperature and the Kelvin scale stand alone, but they reward study after the earlier theory.
6. Water — solutions, solubility, crystals and hardness tie together ideas met so far.
7. Atmospheric Pollution — independent of the rest, so it can be revised at any point.

The heavier practice sits outside the Chemistry book. Simplified Chapter 6 sets 80 counted questions and Simplified Chapter 9 sets 72 — both reward a second pass. Simplified Chapter 1 sets 40, while the Chemistry book’s Chapter 8 sets 25 and Chapter 1 sets 17.

One correction, stated plainly: if you memorise the valency table in Chapter 1 without the Bohr-Bury scheme in Chapter 4, you are memorising instead of understanding. The electron distribution in sections 4.10 and 4.11 is where valency comes from.

A student whose school prescribes Simplified can keep the same order: its Chapter 1 (matter, 40 questions), then Chapter 3 (mixtures), Chapter 6 (water) and Chapter 9 (hydrogen). The Rachna Sagar chapter on this page, Atmospheric Pollution, sits alongside Chemistry Chapter 8 for revision.

Match your textbook to the right chapter

Water, hydrogen and atmospheric pollution each appear in two books on this page, so the table below matches your school textbook to the right chapter. A dash means that book has no chapter for the topic among the ones listed here.
