is there any way to make antimony trioxide from antimony solutions
literally just the title. i really need help on this
35 elements synthesized me in total
bought 15 because of toxicity issues/cant get it from household materials
3 years of this project and still working on catching them all (that's possible)

Probably. What compound is in solution? You may just be able to evaporate off the solvent and then heat the residue in a container open to the air
(outside). Is this for a collection or for synthesis? Depending on the actual compound you may want to throw in an oxidizer like a nitrate or
(per)chlorate.

Yes, I suggest you utfse.
Google: antimony oxide preperation.
First hit.

im sorry Tsjerk, i didnt search that specifically. when i was searching all i seen was just getting it from antimony metal which when i tried didnt
work. i was trying to get it from the oxychloride and it wasnt working. i feel really dumb rn

From atomistry.com (http://antimony.atomistry.com/antimony_trioxide.html), which sources its material from old chemistry journals (some of which, can be quite dated),
to quote:
"Antimony Trioxide, Sb2O3 was known in ancient times....The trioxide may be prepared by the direct oxidation of antimony, by heating in air or in
water vapour; by the action of concentrated nitric acid, in which case a mixture of oxides is obtained; or by fusion with potassium nitrate and
potassium bisulphate. The higher oxides of antimony may be reduced to the trioxide by the action of sulphur dioxide or hydriodic acid.
Many antimony compounds may be decomposed by suitable reagents, yielding antimony trioxide. Thus, antimonyl chloride is completely converted to the
trioxide by treatment with water at 150° C.; antimony salts are decomposed by alkali hydroxides and carbonates, and potassium antimonyl tartrate is
decomposed by the action of salts of weak acids such as borates, acetates, thiosulphates, phosphates, sulphites, etc., trioxide being formed in each
case."
A good path is likely via antimony trichloride, which per Atomistry (http://antimony.atomistry.com/antimony_trichloride.html), to quote:
"Numerous chemical reactions resulting in the formation of antimony trichloride have been described. It may be obtained from metallic antimony by the
action of chlorine, acid chlorides, magnesium chloride and other metallic chlorides. Hydrochloric acid, free from air, does not attack antimony, but
in the presence of air, antimony trichloride is formed slowly; the action is accelerated by the presence of a little nitric acid."
I suspect the action on Sb metal of aqueous CuCl2 (an acid chloride, from CuSO4 + 2NaCl and freezing out the Na2SO4 hydrate) should form SbCl3. Note:
this path mirrors the action of cupric on Sn creating Sn(2+) and cuprous salt at https://www.chm.uri.edu/sgeldart/chm112/112%20Chapter%2019.p... page 29.
Treating SbCl3 with Na2CO3 should create the trioxide.
