Important: JAMB candidates should always verify the latest syllabus through the official IBASS platform because examination information can be updated.

What Is the JAMB Chemistry Syllabus?

The JAMB Chemistry syllabus is a guide showing the Chemistry concepts and learning objectives candidates are expected to study for UTME.

It is not a collection of questions that JAMB will necessarily repeat in the examination. Instead, it provides the scope of Chemistry preparation.

The official syllabus aims to help candidates understand basic Chemistry principles, interpret scientific data, identify relationships between Chemistry and other sciences, and apply Chemistry knowledge to industry and everyday life.

This means candidates should combine memorisation with genuine understanding.

JAMB Chemistry Syllabus 2026/2027

The major areas covered by the official Chemistry syllabus include the following.

1. Separation of Mixtures and Purification

Candidates should understand pure and impure substances, elements, compounds and mixtures.

Important areas include:

• Physical and chemical changes
• Boiling and melting points
• Filtration
• Evaporation
• Crystallisation
• Sublimation
• Decantation
• Magnetisation
• Simple distillation
• Fractional distillation
• Paper chromatography
• Column chromatography

You should understand the principle behind each method rather than simply memorising its name.

For example, filtration can separate an insoluble solid from a liquid, while distillation can be used to separate substances based on differences in boiling points. The official syllabus specifically requires candidates to understand and apply the principles of separation processes.

2. Chemical Combination and Stoichiometry

Stoichiometry is an important calculation area in Chemistry.

Candidates should study:

• Laws of chemical combination
• Law of conservation of matter
• Law of definite proportions
• Law of multiple proportions
• Gay-Lussac’s law
• Avogadro’s law
• Chemical symbols
• Chemical formulae
• Chemical equations
• Relative atomic mass
• Mole concept
• Avogadro’s number

The syllabus expects candidates to perform calculations involving chemical formulae, equations, composition and the mole concept.

Important Mole Formula

Number of moles = Mass ÷ Molar Mass

Therefore:

n = m/M

Where:

• n = number of moles
• m = mass
• M = molar mass

Also remember:

Number of particles = Number of moles × Avogadro’s constant

Avogadro’s constant is approximately:

6.02 × 10²³ mol⁻¹

Practise these calculations regularly.

3. Kinetic Theory and Gas Laws

Candidates should understand the kinetic theory of matter and the behaviour of solids, liquids and gases.

Important areas include:

• Particle movement
• Melting
• Vapourisation
• Freezing
• Condensation
• Diffusion
• Gas pressure
• Temperature
• Volume
• Gas laws

Boyle’s Law

At constant temperature:

P₁V₁ = P₂V₂

Charles’ Law

At constant pressure:

V₁/T₁ = V₂/T₂

When solving gas-law questions, temperature generally needs to be expressed in Kelvin.

Do not simply memorise these formulas. Understand how pressure, volume and temperature are related.

4. Atomic Structure

Atomic structure is another important Chemistry topic.

Candidates should study:

• Atoms
• Protons
• Neutrons
• Electrons
• Atomic number
• Mass number
• Isotopes
• Electron arrangement
• Energy levels

Remember:

Atomic number = Number of protons

And:

Mass number = Protons + Neutrons

Therefore:

Number of neutrons = Mass number − Atomic number

Questions can require you to determine the number of protons, neutrons or electrons from information about an atom.

5. Periodic Table

The periodic table should be studied carefully.

Important areas include:

• Groups
• Periods
• Metals
• Non-metals
• Metalloids

Pay attention to important groups such as alkali metals, alkaline earth metals, halogens and noble gases.

You should understand how an element’s position in the periodic table relates to its properties.

6. Chemical Bonding

Chemical bonding explains how atoms combine to form compounds.

Candidates should study:

• Ionic bonding
• Covalent bonding
• Metallic bonding
• Electron transfer
• Electron sharing
• Valency

• Properties of covalent substances

An ionic bond generally involves electron transfer, while covalent bonding involves sharing of electrons.

You should understand how different types of bonding affect properties such as melting point, solubility and electrical conductivity.

7. Acids, Bases and Salts

Acids, bases and salts are important areas for Chemistry preparation.

Study:

• Properties of acids
• Properties of bases

Examples of common acids include hydrochloric acid, sulfuric acid and nitric acid.

Common bases include sodium hydroxide, potassium hydroxide and calcium hydroxide.

A typical neutralisation reaction can be represented as:

Acid + Base → Salt + Water

Make sure you understand the chemical process, not just the equation.

8. Oxidation and Reduction

Candidates should understand oxidation and reduction, commonly called redox reactions.

Important concepts include:

• Oxidation
• Reduction

Candidates should understand factors affecting the rate of chemical reactions.

These include:

• Temperature
• Concentration
• Pressure
• Surface area
• Catalysts
• Nature of reactants

For example, increasing the surface area of a solid can increase the rate of reaction because more particles are exposed for collisions.

Understand the reason behind each factor.

Important concepts include:

• Reversible reactions
• Dynamic equilibrium
• Equilibrium position

Density

Density = Mass ÷ Volume

Concentration

C = Number of moles ÷ Volume

Percentage Composition

Percentage composition = Mass of element ÷ Relative molecular mass × 100

Percentage Yield

Percentage yield = Actual yield ÷ Theoretical yield × 100

Boyle’s Law

P₁V₁ = P₂V₂

Charles’ Law

V₁/T₁ = V₂/T₂

Writing formulas is not enough. Practise applying them to different types of questions.

How to Prepare for JAMB Chemistry 2026/2027

1. Study With the Official Syllabus

Use the official JAMB IBASS Chemistry syllabus as your checklist. JAMB’s website provides access to IBASS, while the Chemistry syllabus contains the detailed objectives and topics.

2. Divide Your Study Time

Break Chemistry into smaller sections instead of trying to finish everything at once.

For example:

• Monday: Atomic structure
• Tuesday: Periodic table
• Wednesday: Bonding
• Thursday: Mole concept
• Friday: Organic Chemistry
• Weekend: Revision and practice

3. Practise Calculations

Spend time solving mole, concentration, gas-law and stoichiometry questions.

4. Use Past Questions

Past questions can help you become familiar with question styles. However, don’t rely on memorising answers.

5. Revise Your Mistakes

Keep a notebook of questions you get wrong and review them regularly.

6. Understand Organic Chemistry

Rather than memorising isolated compounds, learn them according to:

Functional group → Formula → Naming → Properties → Reactions → Uses

Common Mistakes to Avoid

Studying Without a Syllabus

Random reading can leave important areas uncovered.

Memorising Everything

Understanding chemical principles is more useful than memorising hundreds of isolated facts.

Ignoring Calculations

Calculation questions require practice.

Forgetting Units

Always check whether the question uses grams, kilograms, litres, millilitres, Kelvin or another unit.

Rushing

Read every question carefully, especially questions containing words such as NOT, EXCEPT, CORRECT or INCORRECT.
