Understanding JAMB Chemistry: What You Need to Know

The JAMB Chemistry exam is one of the subjects that students take when they want to enter universities in Nigeria. Chemistry is a science subject, and it is often considered difficult. But with the right preparation and understanding of important topics, you can pass it with good grades.

The exam usually has multiple-choice questions and is designed to test your knowledge of basic chemistry concepts. This means you need to know the main topics and how to answer questions about them.

Key Topics to Study for JAMB Chemistry in 2025/2026

Below are the important topics you should focus on for the JAMB Chemistry exam:

1. Atomic Structure and Bonding

Understanding atomic structure and how atoms bond is one of the most important topics in Chemistry. In this section, you will learn about:

Atoms and Elements: What atoms are made of, and how elements are formed.
Atomic Number and Mass Number: These are the numbers that help you understand elements.
Electron Configuration: How electrons are arranged in atoms.
Ionic and Covalent Bonding: This explains how atoms join together to form compounds.

Knowing how to draw the structure of atoms and how different types of bonds form is very important for JAMB Chemistry.

2. Stoichiometry (The Mole Concept)

Stoichiometry is about measuring the amount of substances in chemical reactions. In this topic, you will learn about:

Moles and Mole Concept: What a mole is and how it is used to measure substances.
Balancing Chemical Equations: How to balance equations to show that mass is conserved during a reaction.
Molar Mass and Avogadro’s Number: These help in calculating the number of particles in a substance.

Stoichiometry questions are very common in JAMB Chemistry, so it is important to practice solving problems related to this topic.

3. Chemical Reactions and Equations

In this section, you will learn about different types of chemical reactions. You should focus on:

Types of Reactions: These include synthesis, decomposition, single replacement, and double replacement reactions.
Exothermic and Endothermic Reactions: Reactions that release or absorb heat.
Balancing Equations: Making sure that the number of atoms on both sides of a chemical equation is the same.

This topic is important because it tests your ability to understand how chemicals react with each other.

4. Acids, Bases, and Salts

Acids, bases, and salts are common in everyday life, and understanding them is essential for the JAMB Chemistry exam. In this section, you should focus on:

Properties of Acids and Bases: How acids and bases behave in water.
pH Scale: The scale that measures the acidity or alkalinity of a substance.
Neutralization Reactions: How acids and bases react to form salt and water.
Salt Preparation: Different methods of making salts.

This topic is very important, and JAMB often includes questions about acids, bases, and salts.

5. Organic Chemistry

Organic Chemistry is the study of carbon compounds. This is a very broad topic, but you can focus on:

Hydrocarbons: These are compounds made of carbon and hydrogen, such as alkanes, alkenes, and alkynes.
Isomerism: When two compounds have the same chemical formula but different structures.
Functional Groups: Specific groups of atoms in organic compounds, like alcohols, aldehydes, and acids.
Nomenclature: The rules for naming organic compounds.

Organic Chemistry can be difficult, but focusing on the key concepts will help you do well in this section.

6. Gases and Gas Laws

In this topic, you will learn about the behavior of gases. You need to understand:

Gas Laws: These are the laws that describe how gases behave under different conditions, such as Boyle’s Law and Charles’s Law.
Ideal Gas Equation: This equation relates the pressure, volume, temperature, and number of moles of a gas.
Real Gases: How real gases behave and differ from ideal gases.

Questions on gases are often found in JAMB Chemistry, so make sure you understand these laws and how to apply them.

7. Solutions and Solubility

This topic deals with how substances dissolve in liquids. You will learn about:

Types of Solutions: What makes up solutions like solid in liquid, gas in liquid, etc.
Concentration: How to measure how much solute is in a solution.
Solubility: How much a substance can dissolve in a solvent at a given temperature.

Having a good understanding of solutions and solubility is crucial for answering questions related to concentration and mixtures.

8. Thermochemistry

Thermochemistry is the study of heat changes in chemical reactions. In this topic, you will learn about:

Heat of Reaction: The heat released or absorbed during a chemical reaction.
Exothermic and Endothermic Reactions: As mentioned earlier, these are reactions that release or absorb heat.
Calorimetry: Measuring the amount of heat involved in a reaction.

Thermochemistry may not have as many questions, but it is still important to understand the basic concepts.

Tips for Studying for JAMB Chemistry

Now that you know the important topics to study for JAMB Chemistry, here are some tips to help you prepare effectively:

1. Use JAMB Past Questions

One of the best ways to prepare for JAMB Chemistry is to practice with past questions. These questions can give you an idea of what to expect and help you learn how to answer them quickly.

2. Focus on Understanding, Not Memorizing

It is better to understand the concepts than just memorizing them. If you understand how things work in Chemistry, it will be easier to answer questions, even if they are worded differently.

3. Break Down Your Study Plan

Don’t try to study everything at once. Break down your study plan into manageable parts. Focus on one topic at a time, and make sure to revise regularly.

4. Study with a Group

Studying with friends can help you understand difficult topics better. You can ask each other questions and explain difficult concepts to each other.

Conclusion

Passing the JAMB Chemistry exam in 2025/2026 is possible if you focus on the important topics we have discussed. By studying topics like atomic structure, stoichiometry, acids and bases, and organic chemistry, you can improve your chances of success. Make sure to practice past questions, understand the concepts, and manage your study time wisely. With hard work and dedication, you can achieve a great score in JAMB Chemistry. Good luck!
