Hello!
I'm just wondering if anyone knows of precipitation pracs (simulations) on the internet? I did a quick google search and came up with theories about the weather!

Thanks for both of those. They look good but I don't think it is really what the teacher is after. The precipitate one (solubility) is a bit time consuming to make up the solutions first, and then they are just in the same beaker without seeing the precipitate (unless I am doing something wrong?). I'll keep looking. The class is in the computer room on Thursday.
