Hi all,
I've been using FeCl3 for longer than I can remember but the solid form is
getting hard to find these days. I'm looking at alternatives such as CuCl2.
Most of the procedure looks pretty straightforward.
What concentration of H2O2 did you use? Was it the commonly available "10
volume" from the pharmacy or do you need something stronger?
