Potato, sodium chloride and acetic acid
I was starting to get bored with the supersaturated salt-in-acetic acid solution and I dropped a potato piece in it. I added 5% hydrogen peroxide and
left it in the solution for around 36 hours.
When I took it out, due to osmosis, it had decreased its size very much: it was around 7cm in length and now it is only 5cm in length. Furthermore,
the colour change has been spectacular: it has turned very bright and white (you can't see the real colour in the photograph, though).
I washed it in ethanol to remove impurities and took the photograph (the one attached).
Some NaCl crystals are beginning to form on the surface.
PS. I'll have to re-size the photograph.
there may be bugs in gfind
