..when I made my solution of Potassium Dichromate I wanted a saturated
solution, so I weighted more dichromate than was possible to get into
solution and stirred. So I now have a truly saturated solution of Pot.
Dichromate (with crystals on the bottom). Providedd that I keep the
temperature of the solution constant (it more or less is), and do not
put my pipet on the bottom, this should work. Or not?
(as I posted before: just starting..;-)..)
