I would like to do a classroom demonstration using plaster of paris (or something similar) shells dissolving in a low pH solution, simulating ocean acidification.
I would like the reaction to happen quite quickly in front of the classroom. What solution could I use to dissolve plaster of paris quickly? It doesn't have to be low pH, but visually simulating it. This will accompany another experiment using Bromothymol blue dye, so I will color the solution yellow. It would be great if the solution was odorless or low odor...
