So what happens if one were to use a chloride instead of a bromide for a re-halogenating bleach? Further, can one use sodium chloride as the chloride, and in what proportion? Some brands of Kosher salt sold in the US contains nothing but sodium chloride. though there are some brands that contain an agent, yellow prussiate of soda, to prevent caking. I suspect these brands are to be avoided if salt can be used in a re-halogenating bleach.
