Hello there!

Welcome to Chemistry with Ease! A virtual chemistry textbook for highschoolers and adults alike. I created this website with the original intentions of helping other students study for chemistry olympiads. Whether you are looking to review for your exams or challenge yourself with some past olympiad questions, this is the place for you! This website covers topics that are typically found in the junior and senior year chemistry curriculum, and up to two years in university. (One year for programmes such as Advanced Placement and International Baccalaureate.) I have adopted part of the curriculum of the IB programme as well as a univesity entry-level chemistry textbook (i.e. Zumdahl and Housecroft.). If you are using this in conjunction with a class, that is fine too. But if you are using this as a stand alone bona fide textbook, I strongly recommend you obtain supplementary materials for your studying.

Technical Details

Chemistry with Ease is a web based textbook built on html codes, to help students visualise, a 3D model of molecules are often embedded using javascript and sometimes flash. Please make sure that you are using a browser that supports such a function.Here is an example of an embedded molecule, see if you can see it, if not, it is an indicator that your current browser might not be compatible. For best user experience, access this reference using a laptop or a desktop.

With your cursor, you can drag, pan and using the scroll function on your track pad/mouse, you can zoom in. Should you encounter any difficulties, please visit the Contact page and drop me a line, I am eager to help. In addition, here are some chemical equations, make sure you can see the different types of arrows and reactants.

$$\ce{N2(g) + 3H2(g) <=> 2NH3(g)}$$

$$\ce{3CO + 7H2 -> C3H8 + 3H2O}$$


This is what in-line maths look like: \(y=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

Content Guide

It is expected that students have a basic understanding of the scientific method, units of measurements and some understanding of basic arithmetics in maths and algebra. It is also strongly recommended that students using this online reference as a self guided course have an understanding of logarithms, geometry, exponentials, and calculus.

The syllabus is laid out as such:

Ch.1 The Chemical Fundamentals

Ch.2 The Quantum Theory

Ch.3 Energy

Ch.4 Chemical Kinetics

Ch.5 Acids and Bases

Ch.6 Chemical Equilibria

Ch.7 Acids and Bases At Equilibria

——End of a typical highschool chemistry course——

Ch.8 Introductory Biochem

Ch.9 Introductory Organic

Ch.10 Chemistry of Inorganic Compounds

Ch.11 Introductory Physical Chemistry

Ch.12 Introductory Analytical Chemistry

Students looking to challenge themselves should complete the whole course, consisting of 12 chapters. Should he/she chooses, certain challenging topics that go beyond 1st year university content is offered as well.

End of chapter tests and problem sets are taken from past IB, AP papers as well as challenging questions (marked with (Contest)) taken from past chemistry contests. They are designed in a way to train the student’s aptitude in solving complex questions.
