Chemistry, brought to life
Interactive simulations
Five carefully crafted simulations for GCSE and A-Level chemistry. Titrations, rates of reaction, organic mechanisms, dynamic equilibrium, and 3D molecular shapes. Every curve, arrow and bond angle is checked against the UK exam specifications. Free to use and free to share.
Virtual Titration Lab
Drip-by-drip acid–base titrations with a real pH solver, live curve and indicator colour change.
Reaction Rates Laboratory
Marble + acid and the disappearing-cross. Arrhenius, collision theory and the Maxwell–Boltzmann distribution.
Organic Mechanism Animator
Step-by-step curly-arrow animations for nine A-Level mechanisms, with a drag-the-arrow quiz mode.
Dynamic Equilibrium Sandbox
Watch reactants and products interconvert, perturb the system and see Le Chatelier's principle unfold in real time.
Chromatography Bench
Paper chromatography of inks and TLC of Anadin Extra under UV. Read off Rf values and identify the unknowns.
3D Molecule Builder
Construct molecules from scratch, see VSEPR at work, read off real bond angles and watch the dipole moment form.
Every simulation here is free to use and free to link to. They are part of Dr Anna Brogden's tutoring practice. If you would like one-to-one support with your chemistry, book a trial session below.
