Will chlorate decompose in a swimmng pool
Hi
I currently have about 20 liters of water that I used to purify potassium chlorate, it is from green cell so no dichromates are present.
Can I just throw it into my swimming pool and wait for a few days as the chlorate ions reduce to chlorine by UV light?

anyone?
Obviously the hypochlorite ion does but as chlorine gets to the +5 oxidation state is Ultra Violet light capable of reducing it back to its elemental
state?

To be honest I don't really think so. Because hypochlorites are generally the most unstable salts of chlorooxo acids. Stability of these goes up the
more oxygens are on the chlorine. So stability is like HOCl < HClO2 < HClO3 < HClO4 and also in reactions with organics chlorate doesn't
react most of the time, at least when in alkaline or neutral medium. But you could easily destroy your chlorate using some HCl.
HCl gets oxidized to Cl2 and water, while your chlorate is reduced to chloride:
KClO3 + 6 HCl -> KCl + 3 Cl2 + 3 H2O

Rad, solved mate!
You're saying throw it in the pool and then throw in the pool acid. HCl.
Thanks Tellurium

You're welcome! I would put in the HCl before throwing it into the pool, because you will have a higher concentration of HCl and the reaction will
proceed faster. But be aware, that you will introduce quite some Cl2 to your pool - I don't know how much a pool normaly has or how big your pool is,
but it will definately destroy the chlorate
