Moderator Note - Moved from this thread : Breakdown of bleach over time by storage temperature - Page 2
So is trade % = % by volume as opposed to % by weight (what's listed on the bottle)? I'm looking at a bottle of bleach that says "Sodium Hypochlorite....8.25%" and "Yields 7.86% Available Chlorine". What am I looking at here with this bleach?
***EDIT*** I put together a formula to figure price per ounce of chlorine so I can compare cost of store-bought to HASA(12.5%). Just need to know which number to plug into the formula.
I had the Trade % wrong for the 8.25% bleach. I've corrected that in my post. It's 8.64%.
