Acid burns occur when strong acids come into contact with the skin or other tissues, causing damage. Common acids that can cause burns include sulfuric acid, hydrochloric acid, and nitric acid. The severity of the burn depends on the acid's concentration, the duration of contact, and the area affected. Symptoms of acid burns may include redness, pain, blistering, and in severe cases, tissue necrosis. Immediate treatment involves rinsing the affected area with water to dilute the acid and remove it from the skin. Seeking medical attention is crucial for proper evaluation and care.
