B. Ionic Charge
Note that Simulator #1 below has +1 and -1 ions and that Simulator #2 has +2 and -2 ions (if the model containers do not appear to be aligned correctly, side by side, maximizing the screen size may help).
Instructions for running simulations:
1. Click Run in both of the simulators below. Observe for about 10 seconds.
2. With the model continuing to run, increase the temperature on both models by moving the slider one tick mark to the right. Observe for about 10 seconds.
3. Repeat step 2 until you reach the highest temperature (make sure to observe the model at each tick mark).
