Yes, and corpses turn to ashes. But just as the mafia doesn't dump a body in the back yard and expect to see nothing but ashes blowing away in the wind the next morning, most of us don't expecting to put out a few gallons of bleach solution tonight and have all of the water evaporated and all of the bleach de-activated by morning. Don't believe everything that the manufacturers of Clorox and Tylex tell you on their container labels.
The water takes a very long time to evaporate and the bleach is not all deactivated when the water finally does evaporate. Sodium hypochlorite is unstable, but nowhere near the extent that you assume.
I'd suggest using Google with search terms such as: reactivate "sodium hypochlorite" OR bleach
I'd also suggest talking with a few carpet experts, including carpet cleaning specialists. There are many naive carpet owners who believe that the bit of bleach that they dripped on their carpet will quickly and completely "turn to common table salt." Often over the course of months they discover that the once slightly bleached dots on their carpet are turning lighter and lighter. Why? Because the bleach is continually "reactivated" by water tracked onto the carpet or even by ambient moisture.
Other homeowners spray outdoor items with one of the common bleach- based cleaners and carefully follow the manufacturers advice to avoid tracking the liquid into the house. But a few days later, when dew or light rain is on the ground, they track the reactivated bleach through the house, with disasterous results to their carpets.
