antimony trioxide


I acquired some Sb2O3 really cheaply. Any suggestions of what I might do with it?

Antimony triiodide SbI3 is a beautiful red compound when made by reacting antimony metal with iodine in xylene; it will be interesting to see what you get if you react a solution of an antimony salt with a solution of potassium iodide. Atomistry says Sb2O3 will dissolve in concentrated sulphuric acid and hydrochloric acids but whether that will give you a soluble sulphate or chloride I don't know.

You can make potassium antimony tartrate, an interesting compound that forms very pretty crystals, and was historically used to induce vomiting:

I agree. It's a very easy synthesis. If you need some help, let me know, I have made it many times (even GMP and meeting USP-NF specs!).

If you have CsCl and conc. HCl, then you can do a really interesting experiment and make Cs3[SbCl6].Cs[SbCl6], which is a mixed oxidation state compound, with a deep blue color:

Potassium antimonate, which can be used as test for sodium ions (sodium antimonate is insoluble):

Sodium thioantimonate:

I can offer GC analysis of samples. Just U2U to me for more info.

You can combine it with chlorine to form antimony trichloride, then melt the trichloride at 73.4C and pass more chlorine through it to form antimony pentachloride. SbCl5 melts and carbonizes plastic materials, which is pretty cool.
