Look up any element to see full electron configuration, noble gas shorthand, orbital box diagram, valence electrons, and oxidation states.

Phase Diagram & Heating Curve Explorer

Interactive P-T phase diagram for water, CO2, ethanol, and nitrogen. Explore heating curves, triple points, and colligative effects.

Chemistry Labs

Virtual Labs for AP Chemistry Investigation

Each lab includes a guided experiment workflow, data collection table with CSV export, and a lab report panel with PDF export. Suitable for the AP Chemistry lab requirement.

Gas Laws Lab

Investigate Boyle's, Charles's, and Gay-Lussac's laws and the combined gas law with interactive pressure-volume-temperature controls.

Titration Lab

Simulate acid-base titration with a virtual burette. Watch pH curves develop in real time, find equivalence points, and compare strong and weak acid behavior.

Calorimetry Lab

Mix substances at different temperatures, calculate specific heat, and compare coffee cup and bomb calorimeters. Model heat loss.

Equilibrium Lab

Explore chemical equilibrium with Le Chatelier's principle. Adjust concentrations and temperature to watch Q approach Keq with ICE tables.

Thermochemistry Lab

Build enthalpy diagrams, apply Hess's law across multiple reaction paths, and calculate enthalpy changes from bond energies.

Chemical Kinetics Lab

Simulate reaction rates with the Arrhenius equation. Adjust concentration, temperature, and catalysts to observe how rate constants change.
