How to use the virtual lab and simulations

Choose Object › Chemistry › Simulations or Virtual lab. Tabs switch between Gas laws, pH scale, Equilibrium, Build a molecule and Virtual lab.

Virtual lab

  1. Choose Main menu › Object › Chemistry › Virtual lab.

  2. Put glassware on the Bench: a Beaker, Volumetric flask or Buret.

  3. Select a vessel, set how many mL to Take, and take a solution from the Stockroom, such as 0.1000 M HCl, 0.1000 M NaOH or an acetate buffer. The bench reads the pH of the selected vessel.

    The Virtual lab: the stockroom of solutions, the bench and Set up a titration.The Virtual lab: the stockroom of solutions, the bench and Set up a titration.

  4. Set up a titration starts a titration on the bench. Undo takes back a step and Clear the bench starts over.

Simulations

The same window has Gas laws, pH scale, Equilibrium and Build a molecule. In Gas laws, move the amount, temperature and volume and watch the pressure, from PV = nRT.

Gas laws: 1.0 mol at 298 K in 24.5 L gives 1.00 atm.Gas laws: 1.0 mol at 298 K in 24.5 L gives 1.00 atm.
