👉 The "acid weapon" refers to the corrosive effects of strong acids on living tissues and materials. Strong acids, such as hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and nitric acid (HNO₃), can cause severe damage to biological tissues like skin, eyes, and internal organs upon contact. They disrupt cellular structures and functions by breaking down proteins, lipids, and nucleic acids, leading to tissue necrosis and inflammation. In medical contexts, exposure to these acids can result in burns, ulcers, and even systemic toxicity if not promptly treated. Similarly, in industrial settings, acid spills or leaks pose significant risks to safety and require immediate response measures to mitigate harm.
