Concentration Simulation, Worksheet and Questions

        This tutorial has an HTML 5 simulation from pHet embedded into it.  The corresponding worksheet is shown below and there is a an associated quiz.

Concentration Worksheet

/

Concentration

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

Salts and Solubility simulation

Follow this link to the Salts and Solubility simulation.

I am working on embedding the simulation.

pH Scale

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
