Teachers at professional development drew our attention to an issue with the solutions sims. In particular, soluble compounds were showing masses/molar quantities moving into and out of solution that were grossly out of scale with what would be expected in reality.

To fix this problem, I have implemented custom logic for these sims where the 1 particle to 1 mol ratio is altered to give smaller shifts in mass/moles as single ions move into and out of solution.

This will never be quite perfect, since the quantity of particles in the simulation window are intended to stand in a proportional representation of a real solution and we will be limited by the disparity in quantities between how many particles we can simulate (50-100) and the quantities on the submicroscopic scale (order of 10^23).
