Chlorine bleach, upon evaporation, leaves a white residue. What is
it? Chlorine itself will dissipate from water solution, given enough
time, but evaporation of bleach solution definitely leaves white
powder. I thought that was sodium hypochlorite, which is shipped for
swimming pool treatment as a solid. I thought it was liquid only in
water solution (bleach).

BTW, there is no nitrogen in bleach.
