Chemistry you can see, not just memorize
Free, open tools for students who find chemistry hard to hold in their head — an interactive periodic table, mnemonics for the elements, and a sandbox where real reactions actually happen.
iLabs — short for intelligent labs — is a free set of browser-based chemistry learning tools built for students: a physics reaction sandbox with 200+ real balanced equations, an interactive periodic table of all 118 elements, a learn section with concept lessons and guided practice (the mole & molar mass, balancing equations), a page on atomic models, element mnemonics, mini-games and a 200-question quiz. No sign-up, works on any device, and always free.
Reaction sandbox
Drop substances together and watch real, balanced reactions play out — combustion, displacement, precipitation, titration, electrolysis and more, with NCERT lessons built in.
Interactive periodic table
Recolour the whole table by category, block (s/p/d/f), physical state, radioactivity or origin. Click an element for facts, electron configuration and a Bohr diagram.
Learn chemistry
Concept lessons that then make you practise — the mole and molar mass, and balancing equations with 130+ problems. Plus atomic models, mnemonics and a constants table.
Chemistry games
Element Detective, Periodic Table Rush, Symbol Match and Higher or Lower — quick games that drill the periodic table without feeling like revision.
Why this exists
Most students don't struggle with chemistry because it's hard — they struggle because it's taught as a list of things to memorize. Equations, element order, reactivity trends, colour changes: all abstract, all on paper.
iLabs turns those into something you can look at and play with. The periodic table is colour-coded so the patterns jump out. The mnemonics give you a hook for the order. The sandbox lets you actually run the reaction and see the fizz, the flame, the precipitate — then shows you the balanced equation for what just happened.
It's free, it works in any browser, and it always will be. If it helps and you'd like to support the hosting, there's a coffee link below — entirely optional.
Frequently asked questions
What does iLabs stand for?
iLabs is short for intelligent labs — free, interactive science labs for students. It starts with chemistry; physics and maths labs are planned.
What is iLabs?
A free set of browser-based chemistry learning tools: a physics reaction sandbox with 200+ real balanced equations, an interactive periodic table of all 118 elements, a page on atomic models, element mnemonics, mini-games and a 200-question quiz.
Is iLabs free? Do I need an account?
Every tool is free with no account or sign-up. The site is supported by unobtrusive ads and an optional Buy Me a Coffee link.
Who is it for?
School and early-college chemistry students — especially those following the NCERT syllabus for classes 9 to 12 — and anyone who learns better by watching a reaction than by reading about one.
Are the reactions real chemistry?
Yes. All reactions are real, with balanced equations, correct products and realistic conditions such as needing heat or a catalyst. Even deliberate non-reactions — like gold resisting a single acid — are modelled.
Does it work on a phone?
Yes, it runs in any modern mobile or desktop browser. The sandbox is best on a larger screen, but the periodic table, mnemonics and quiz work well on a phone.
