ChemLab - Chemistry Lab

ChemLab turns your iPhone or iPad into an interactive chemistry lab for learning, practice, and exploration.

Add reagents to the beaker, heat the mixture when needed, and watch reactions come to life through bubbles, precipitates, flame, color changes, temperature changes, and synthesized sound effects. From preparing hydrogen and carbon dioxide to neutralization, displacement, precipitation, indicator color changes, combustion, and catalytic decomposition, ChemLab helps make core chemistry concepts easier to see and understand.

Explore freely or follow guided challenges. Challenge Mode includes step-by-step missions such as preparing hydrogen, testing chloride ions, extracting copper by displacement, producing oxygen with a catalyst, igniting magnesium, and observing the reaction between sodium and water.

ChemLab also includes an equation-balancing practice mode. Adjust coefficients, check atom conservation in real time, and learn why the simplest whole-number ratio matters.

Key Features:
- Free experiment mode with 39 reagents and 42 simulated reactions
- Visual effects for bubbles, precipitates, flame, smoke, glow, color changes, and heat
- 10 guided lab missions with progress tracking and points
- 12 equation-balancing challenges with real-time atom checks
- 20 achievements across bronze, silver, gold, and platinum tiers
- Expandable experiment reports with shareable poster images
- Lab book history that automatically saves completed reactions

ChemLab is designed for students, teachers, and anyone who wants a safer, more visual way to review basic chemistry reactions. It is an educational simulation and does not replace real laboratory instruction or safety training.
