In a solution with pH rising over 6.0 the proportion of hypochlorous acid declines from virtually 100% down to almost 0 at pH 9.0. 6.2<pH<8.2, and 11.3<pH<13.3 (allowing for buffering of pKa ±1 pH units). As a strong oxidizing agent, it reacts with reducing agents when heated to generate heat and products that may be gaseous (which will cause pressurization in closed containers). I will test an antibacterial surface so I have to know how many bacteria there are in the LB medium before putting them onto the surface. The interest in metal cation perchlorate interactions with photosensitive ligands has increased due to the development of highly specific fluorescence indicators. I also suspect that the caking of my hypochlorite solution is due to the by-product of the hypochlorite.
