Your right, it's not fair. Plus, if I thought I was so enclined to do so, I would experiment to find a suitable reaction on a scale that is actually worth a damn. I only see the simple bichromate being scalable. Although, I am bound to screw somthing up. Not everything is always scaled up in the same proportions as teh original reaction. I have a problem figuring out that part.
Hypo expresses a lot of shared frustrations. However, I am more partial to the V2O5 and sulphanilic acid doped bichromate. That Alumina/KMnO4 reaction looks good, but I know I would screw that up seeing as I would have to scale it 100x. Also I don't like the idea of ordering stuff like permanganate. Several places I know of require DEA form for it now.
Ozone has always looked awseome to me. I love electrolytic experiments. However, determining ozone concentration and other stuff is quite difficult. Besides my recirculator only has markings down to -20. It turns past that enough to count to about -120. This can't be right and the thermostat probably doesn't function at this setting? I have never tried to get it below -15. The ozone reaction requires temps of -80.
I have never even seen sulphanilic acid preparation or at the chem supply. Everything else it on too small a scale liek thae vanadium.
My purpose in reuse is mostly from not wanting to throw Cr salts into the enviroment. I also want to recycle it so that I can use it again. I like the idea of being able to have reusable chemicals so that lifetime stockpile of chems can be kept in a few small bottles
Also, after reading a post in teh metals finishing forum, sodium chromate can be made by electrolytic oxidation into NaOH solution. The well known basic electrostrip. So I guess to save teh expensive H2O2, one can make the chlroide salt and electroplate it onto a carbon rod and reverse into NaOH.
