Chemistry Quiz: Test Your Knowledge of Elements and Reactions

The chemistry quiz on Quizoland offers 90 questions to explore the periodic table, chemical reactions, pH, and organic chemistry. From the foundations laid by Lavoisier to Mendeleev's work, chemistry explains the matter all around us. This quiz is part of our science quizzes category, which brings together all the scientific disciplines. You play right in your browser, no sign-up required, and it's free.

From the Periodic Table to Chemical Reactions

The 118 elements of the periodic table are at the heart of chemistry. Hydrogen, oxygen, carbon, iron, gold: each element has a symbol, an atomic number, and unique properties. The quiz questions also cover chemical reactions: combustion, acid-base neutralization, oxidation-reduction. You'll discover how atoms combine to form molecules like water (H2O) or carbon dioxide (CO2).

pH, Acids, and Bases: The Fundamentals

Understanding the pH scale means telling an acidic solution apart from a basic one. Vinegar contains acetic acid, and gastric juice contains hydrochloric acid. Sodium hydroxide, on the other hand, is a strong base. The chemistry quiz tests your grasp of these essential concepts, from the definition of neutral pH (7) to neutralization reactions.

Try the Chronological Format

Want to mix things up? The chronological quiz asks you to put events or discoveries in order. It's ideal for brushing up on the history of science: Wöhler's synthesis of urea (1828), the Curies' discovery of radium (1898), and Mendeleev's publication of the periodic table (1869).

Score, Timer, and Overall Leaderboard

Every quiz gives you a score out of 10 and tracks your response time. You can compare your performance with other players on the overall leaderboard. For a daily challenge, check out the quiz of the day: a new set of questions every morning.
