Virtual labs

93 experiments

Run chemistry experiments in 3D: change the conditions, watch what happens, and read the numbers behind it.

General chemistry (3)

Weighing a chemical reaction: conservation of massLet limestone react with acid in a flask on a balance, then repeat with the flask open — and explain the difference.Lower secondary10 min Solids, liquids, gases: a particle viewCool the particle box and squeeze the piston to compress a gas into the packing of a liquid, then a solid.Lower secondary10 min Preparing a solution of known concentrationWeigh copper(II) sulfate, dissolve it in water and see how the amount of solute controls the concentration.Lower secondary10 min

Inorganic chemistry (2)

Activity series: zinc versus copperDip a zinc strip into blue copper sulfate and watch red copper grow while the blue fades.Lower secondary15 min Hydrogen by electrolysis of waterAdd a pinch of sodium hydroxide to water, switch on the current, and collect twice as much hydrogen as oxygen.Lower secondary15 min

Organic chemistry (1)

Burning hydrocarbons: signs of a chemical changeIgnite methane, ethylene, acetylene and benzene in turn; compare the flame and the products each fuel leaves behind.Lower secondary12 min

Physical chemistry (1)

The Tyndall effect: is it a solution or a colloid?Shine a narrow beam through water and through a colloidal sol: only the colloid shows a glowing path — the classic test for particle sizes between 1 nm and 1 μm.Lower secondary10 min

Polymer chemistry (1)

Watching a hydrogel drink waterTrap charged groups inside a gel boundary and watch water molecules rush in — the molecular engine behind super-absorbent materials.Lower secondary12 min

Virtual experiment: a simplified model to build intuition. It does not replace real lab work or safety training; never repeat chemistry at home without supervision.
