Hello everyone! I am a newbie here, so if you can direct me to the right place, it's much appreciated.
I am a science teacher and we're working through a set of chemistry experiments together with my students, but I am not a chemist by background rather a mechanical engineer who likes chemistry!
Anyway, we're doing an experiment and hit a snag. We're doing a cold light experiment using luminol, sodium hydroxide, hydrogen peroxide and (here's the question) K3Fe(CN)6. The question is: can K4Fe(CN)6 be substituted for K3Fe(CN)6? Or I guess my real question is, how different is K4Fe(CN)6 and K3Fe(CN)6 in a reaction? I'd really like us both to learn from this, so any help you can provide is appreciated.
Thanks so much.
