When it is mixed with dilute hydrogen peroxide in the presence of a metal ion. The theoretical pH’s below are for ammonia in pure water at 77F. Google Patents WO2000034551A1 - Cleaning solutions containing citric acid and uses thereof Contains not less than 1.6 g/l and not more than 1.8 g/l ofNH3 (Mr 17.03). Aqua Ammonia is also known as ammonia solution, ammonium hydroxide. Typically, the pH of an ammonia solution will be between 11 and 12, compared with a pH of about 14 for sodium hydroxide solutions.
Large volumes of water dilute ammonia, but form highly corrosive ammonia hydroxide solution. Ammonia will follow the wind direction and track along low valleys until it dissipates. WO2000034551A1 - Cleaning solutions containing citric acid and uses thereof The Scale of Common Household Cleaning Supplies Bleach: pH 11-13 Ammonia: pH 11-13 Borax & Baking Soda: pH 8-10 Acidic Cleaning Products: pH < 7. Rain dissipates ammonia releases (contain the runoff until the pH is in the 7 to 9 range).
