I've been using that recipie to make some ferrofluid for a school project. I've been having trouble at the stage where the ammonia is added. Namely, I don't know what color it is supposed to turn after I add the ammonia. I was under the impression that it was supposed to be black but all I'm getting is this muddy orange color. Any advice?
(by the way, how much FeCl3 are you using in the reaction with steel wool to FeCl2? With the advertised 10mL FeCl3 and 10 mL distilled with generous amounts of steel wool, it only takes me about 10 minutes to get it to the bright green color and a few more minutes until its the aqua color.)
