Welcome to our collection of free chemistry simulations, made to help students learn chemistry in a fun and easy way! Instead of just reading about chemical reactions and topics in a textbook, you can try them out yourself with our interactive chemistry tools — no cost, no downloads, and no sign-up needed. This chemistry lab online simulations page has everything from mixing acids and bases to learning about atoms, molecules, and how chemical equations work. Our chemistry simulator lets you click, drag, and experiment just like in a real lab, but safely from your computer or phone. If you've tried PhET simulations chemistry before, you'll feel right at home here, since our chemistry simulation software works the same way — it's simple, visual, and made for students of all ages. Whether you're in middle school just starting to learn chemistry or in high school studying for a big exam, these chemical simulation activities make tricky topics easier to understand by letting you see and do the science yourself. Explore, experiment, and have fun learning chemistry — all for free, anytime you want!
