Safe, engaging chemistry experiments with realistic physics simulations. From titrations to combustion reactions, all without the hazards.
Chemistry is hands-on by nature. But traditional labs face challenges: limited equipment, safety concerns, time constraints, and the impossibility of repeating expensive experiments.
WhimsyLabs virtual chemistry lab solves these problems with physics-accurate simulations that let students practice titrations, observe reactions, and explore molecular structures, safely and as many times as needed.
Our growing library covers key curriculum topics across GCSE, A-Level, IB, and beyond
Master the precision of titration technique with realistic burette controls and colour-change indicators.
What students do: Fill the burette, choose an indicator, and run the titre down to a colour change they have to judge themselves. Concordant results need repeating, because the first run is rarely the good one.
Observe exothermic and endothermic reactions, precipitation, and neutralisation in real-time.
What students do: Change concentration, temperature or surface area and watch the rate respond in real time. Nothing is on rails, the reaction runs on simulated chemistry, so the data has scatter in it.
Safely explore combustion reactions, flame tests, and energy release measurements.
What students do: Burn fuels under a calorimeter, lose heat to the room, and find out why the measured enthalpy never matches the data book.
Investigate electrolytic cells, electrode reactions, and Faraday's laws of electrolysis.
What students do: Wire the cell, pick the electrodes, and identify what collects where, with electrode choice actually changing the products.
Reagents in the lab carry their real hazards. Concentrated acids burn, solvents catch, and gases build pressure in a sealed vessel, and students meet all of it, with consequences that follow from what they actually did.
That is the part a physical school lab cannot teach. Technicians remove the dangerous reagent before the lesson starts, so students never learn what makes it dangerous. Here they can get it wrong, see what happens, and try again.
WhimsyCat, our AI tutor and assessor, watches how students work, burette technique, swirling, indicator choice, endpoint judgement, and grades the process, not just the final figure. Follow-up questions are tied to each student's own results, so answers can't be copied from a chatbot.
There is no student chat window: WhimsyCat infers everything from actions in the lab. Teachers get a skill-by-skill breakdown covering technique, safety, data collection, and scientific communication.
Because a simulation that always gives the right answer teaches students that experiments always give the right answer.
Complete Safety. No risk from corrosive acids, toxic gases, or open flames. Students can experiment freely without danger.
Unlimited Repetition. Repeat experiments as many times as needed. No wasted chemicals, no restocking, no cleanup.
Instant AI Feedback. WhimsyCat AI tutor guides students through techniques and catches mistakes before they become habits.
Real-Time Data. Generate accurate graphs and data tables automatically. Focus on interpretation, not manual recording.

| Runs per student | Unlimited | One, if the class is lucky |
| Cost per repeat | None | Reagents and technician time |
| Dangerous reagents | All of them | Removed before the lesson |
| Evidence of technique | Every action logged | Whatever the teacher saw |
Our chemistry simulations map directly to examination specifications, ensuring every experiment reinforces required practical skills.
Yes, the experiment library covers the major exam-board required practicals, including acid–base titrations, electrolysis, and energy changes. Virtual runs are ideal for building technique before assessed physical practicals; check your exam board's guidance on what may be assessed virtually.
That is the point: reactions too hazardous or expensive for a school lab, concentrated acids, vigorous combustion, are fully simulated, complete with realistic hazards and consequences, so students build real risk awareness with zero real risk.
Yes. Reactions run on simulated chemistry over time, determined by molarity, pH, and reactivity, with impurities and sample-to-sample variation, so no two runs are identical, just like a real bench.
Our complete guide to virtual chemistry labs covers lesson planning, exam-board fit, and how teachers combine virtual and physical practice.
