not sure what i made
i was reading about getting I2 from providone iodine and was playing around with it. i had read that the providone was soulable in xylene so i mixed
the iodine with xylene and removed the xylene layer after a while then mixed hcl with the iodine solution. later i mixed in some sodium hydrochloride
and got a yellow solid floating in a clear liquid. question is what is that solid?

That could be iodine. THe hypochlorite oxidized the iodide ion to iodine.

I've had the same problem. Might be the tribromide ion. Or another halohalide.

1)If it were the tribromide ion, where would the bromine come from?
2)not a halohalide. ICl is black or red, and I doubt ICl3 which is orange-yellow and crystaline would form. Also, interhalogen compounds dont like
water.
3)it could be an oxidation product of povidone.
F. de Lalande and M. Prud'homme showed that a mixture of boric oxide and sodium chloride is decomposed in a stream of dry air or oxygen at a red heat
with the evolution of chlorine.

If there is any ethanol, acetaldehyde or a compound with CH3CO-C in it basic iodine will produce iodoform. Yellow solid, characteristic smell,
insoluable in water. Hypochlorite normally has a large excess of hydroxide and will reoxidise iodide to iodine to produce a larger yeild of iodoform.

My guess would be that some povidone crystallized with a bit of iodine in it.
