Frequently Asked Questions
Technical and pedagogical details about our chemistry virtual labs.
How does OpenLabs simulate chemical equilibrium and reaction rates?
OpenLabs utilizes law-of-mass-action kinetic differential equations coupled with the Arrhenius equation to calculate real-time forward and reverse reaction rates, equilibrium concentrations, and Le Chatelier temperature/pressure shifts.
Are the titration pH curves calculated dynamically or pre-rendered?
Every titration step calculates the exact ionic equilibrium and Henderson-Hasselbalch buffer equations dynamically based on titrant volume, conjugate acid/base dissociation constants (Ka/Kb), and autoionization of water (Kw).
Is OpenLabs chemistry aligned with CBSE Class 11 & 12, AP Chemistry, and IB Chemistry?
Yes. All experiments follow standard syllabus practicals including qualitative salt analysis, volumetric acid-base titrations, chemical kinetics, and standard reduction potentials.
Can I export reaction data, molarity graphs, and titration data?
Yes. All data streams, pH curves, and spectrophotometric absorbances can be exported as structured CSV files for lab reports and statistical verification.
Is the OpenLabs chemistry laboratory free for schools and universities?
Yes. All chemistry experiments, reaction builders, and 3D molecular models are 100% free and open for educational use.
