⚗️ Chemistry
Interactive simulations and tools for AP Chemistry. Each one is designed to make a concept click — not just read about it.
Kinetics & Reaction Dynamics
Reaction Energy Profiles
Manipulate activation energy and enthalpy on an interactive energy diagram. Visualize transition states and the effect of catalysts. (Unit 5.6)
Launch → 💥Collision Theory
See how temperature, concentration, and orientation affect effective collisions and reaction rates. Connects to Maxwell-Boltzmann distributions. (Unit 5.5)
Launch →Equilibrium
Le Chatelier’s Principle
Apply stresses — concentration changes, pressure shifts, temperature changes — and watch the system respond. Interactive Q vs. K visualizer. (Unit 7.9)
Launch → 🧮ICE Table & Equilibrium Concentrations
Step-by-step guided ICE table solver with feedback at each stage. (Unit 7.7)
Launch →Acids, Bases & Buffers
Titration Curve Simulator
Generate and explore titration curves for strong and weak acid-base pairs. See exactly where the equivalence point and buffer region appear. (Unit 8.5)
Launch → 🛡️Buffer Properties Explorer
Add acid or base to a buffer and watch pH resist change. Adjust concentration and conjugate ratio to see how buffer capacity shifts. (Unit 8.8)
Launch → 🔢Henderson-Hasselbalch Calculator
Interactive pH = pKa + log([A⁻]/[HA]) tool with guided practice problems. (Unit 8.9)
Launch → ⚗️Buffer & Henderson-Hasselbalch Visualizer
An interactive visualizer for buffer solutions, titration curves, and the Henderson-Hasselbalch equation. Explore how weak acid-strong base and weak base-strong acid pairs behave across pH ranges, locate the equivalence point and half-equivalence point, and see how pKa, conjugate acid-base pairs, and buffer capacity respond to real-time changes — no calculations required.
Launch →Spectroscopy & Measurement
Thermodynamics
Hess’s Law Interactive
Combine chemical equations to find overall ΔH. Step-through scaffolding with Hess’s Law practice. (Unit 6.9)
Launch → 🌡️Gibbs Free Energy & Favorability
Interactive ΔG = ΔH − TΔS tool showing how temperature flips spontaneity across all four ΔH/ΔS combinations. (Unit 9.3)
