For a science/engineering project we are taking pool water (disinfected), filtering to 0.1 microns, and pumping to the kitchen. Of course there is still 5 ppm of chlorine present so we want to neutralize the chlorine. Asorbic acid in the form of orange juice neutralized the chlorine, but I understand that it also creates some amount of HCl. This method is used to neutralize chlorine in water being introduced into ponds, rivers, etc. so that the chlorine does not kill the fish.
Could the asorbic acid actually create enough HCl to be dangerous, how can I test this, and what is acceptable? I used a standard pool testing kit to test the chlorine.
