making sodium iodate from sodium iodide
using electrolysis of sodium iodide
http://www.youtube.com/watch?v=LGwPfo_eunY
this video shows Electrolysis of Potassium Iodide
and shows iodine being produced iodine does not dissolve in water very well if at all but it does in hydroxide solutions slowly. in the iodine to
sodium hydroxide reaction.
-So does the electrolysis of sodium iodide eventually yeild sodium iodate?

Or you can just mix bleach, NaOCl, with NaI.
(3)NaOCl + NaI --> (3)NaCl + NaIO3

or you can just buy the bleach:
It is really quite inexpensive, can be found in your local supermarket, at comes in NaOCl concentrations between 4-9%.
Taylor's bleach is 8-10 % sodium hypochlorite solution, and a 5L container costs only £1.65

Iodine will redissolve in the Iodide soulution forming the TriIodide I3- anion. That reacts with the NaOH (formed at the other electrode) as follows;
I2 + 2NaOH -> NaI + NaIO + H20. If the soultion is warm, The KOI will form NaIO3 and NaI (which will be reused), analagous to the standard Chlorate
production. YMMV.

Iodate can be made from iodine by refluxing with acidified chlorate solution, followed by neutralization. I did a video of this a while back. I was
told this same procedure will work with iodide instead of iodine however I cannot confirm that from my own experience.
