Acids/Bases Simulations - before and after
In Unit 8, Simulation 2, Sets 1-4, it would be helpful if students could see the "before" image of the reaction for longer; the reaction happens very quickly. Additionally, slowing down the reaction (i.e. pausing immediately and dragging the speed slider to the minimum value) doesn't seem to actually work.
Would we be able to have a play button instead of auto-play for all the simulations? This would solve issues around drawing before and after images.
