Hi Everyone, I need some help replicating a solution that I don't want to have to keep buying from the manufacturer. I use the solution to make a half gallon (2 L) of Hypochlorus Acid for cleaning. I have some basic chemistry knowledge but not much. The solution comes in 2.4 fl oz (3.0 wt oz) packets and state active ingredients of 25.88% Sodium Chloride and 74.12% other ingredients. I know one of the "other" ingredients is Glacial Acetic Acid. I'm assuming I messed up the math. My plan was to calculate out the sodium chloride, add it to the water and then add Glacial Acetic Acid until the PH's match. I came up with 18.37 g NaCl to 71 ml water. If I take 71 ml of water and mix in 18.37 g sodium chloride, it seems like it's too much. The solution from the company is completely clear, and even heating the water I can't get that amount of salt to dissolve in that amount of water where it comes out clear. I'm not sure if I should subtract the amount of water that is equal to the amount of salt in my solution either, but in my head it makes sense to do so to make the overall amount of the solution stay the same. The company's solution has a PH of 2.65 @ 20.1 degrees C. I'm also adding anywhere from 1 to 2 ml of the Glacial Acetic Acid to get the PH's to match.
I've been at this for probably a year now just slightly modifying the ingredients, but after mixing the 2.4 oz solution of water, NaCl and Glacial Acid to the half gallon of water and doing electrolysis the Hypochlorus Acid solution I make never comes out to match the 1100 ppm total available chlorine that the company's solution creates. Can someone point me in the right direction please?
Thanks!
