Phosgene reaction with water
WebEffects have been varied, though largely temporary. Phosgene is only slightly soluble in water; however, it rapidly hydrolyzes to form carbon dioxide (CO2) and hydrochloric acid … WebPhosgene reacts with water in the lungs to form hydrochloric acid, the main damaging chemical (Borak and Diller, 2001). Chlorine reacts with water inside the lungs to form hypochlorous acid that causes severe damage to lung tissue. Chloropicrin is a milder and non-lethal chemical that irritates the mucous membrane (Pesonen and Vähäkangas, 2024).
