What happens when you mix hydrochloric acid with sodium hydroxide? Just pick the two substances and find out. **ChemLab** uses AI to predict what happens when any two chemicals meet, and to solve any chemistry problem from a photo β delivering the balanced equation, observable effects, hazard information, and a full step-by-step worked solution. **Mix Any Two Substances** Choose from 36 common chemicals β acids, bases, salts, metals, oxidizers, and organic compounds β and tap React. ChemLab instantly returns the balanced equation, reaction type, observable effects, hazard level, safety precautions, and a surprising fun fact about the reaction. **Solve Chemistry Problems** Take a photo of any chemistry question and get a full step-by-step solution β topic, given data, key formula, worked calculations, and final answer. Powered by Google Gemini AI. **Experiments, Flash Cards & History** Explore 8 interactive simulations across pH and titration, gas laws, solution chemistry, and electrochemistry β all with live sliders and real-time visualisations. Study with 44 built-in flash cards and revisit saved reactions in your personal history anytime. **Perfect For** β’ High school and university chemistry students β’ Anyone curious about what chemicals do when mixed β’ Students preparing for exams or lab reports β’ Teachers looking for quick, visual chemistry demonstrations **About Chemical Reactions** ChemLab covers the reactions found in a standard chemistry curriculum: acid-base neutralisation, redox reactions, precipitation, combustion, and gas-forming reactions. Results are generated by Google Gemini (via Replicate) and are for educational reference only. Never attempt real chemical reactions without proper supervision, safety equipment, and training. **Privacy First** All reaction history is stored locally on your device. Photos and substance selections are only sent for AI analysis and are never stored on any server.

Verdict
The clearest difference is in-app purchases: ChemLab AI at none against pH Lab's 1. ChemLab AI also leads on ads (none vs shown) and iOS requirement (17.0 vs 26.0). On price and device support there is nothing between them.
