I have some unopened Clorox bleach bought over a year ago at 8.25% NaOCl and read on Wikipedia that bleach naturally decomposes according to
3 NaOCl (aq) -> NaClO3 (aq) + 2 NaCl(aq)
Now, while there potentially might be some further decomposition as
2 NaClO3 (aq) -> 2 NaCl (aq) + 3 O2 (g)
Would I be at risk of filling the air with toxic chlorate intermediates after using this bleach to clean up an ultrasonic ("cool mist") humidifier?
