In forensic toxicology, which acid is commonly associated with yellow discoloration of the stomach mucosa?

• A. Hydrochloric acid
• B. Acetic acid
• C. Nitric acid
• D. Carbonic acid

Answer: (C)

The acid that is commonly associated with yellow discoloration of the stomach mucosa is nitric acid. When nitric acid is ingested, it can cause severe corrosive injury to the gastric mucosa, resulting in discoloration. This yellow color is attributed to the presence of nitric acid and its degradation products, which can lead to necrosis and inflammation of the stomach lining. Hydrochloric acid, while also corrosive, does not typically produce the same distinct yellow discoloration seen with nitric acid, as its effects on the mucosa are more likely to result in a different appearance. Acetic acid, known for its common presence in vinegar, would not cause the same level of injury or discoloration associated with nitric acid. Carbonic acid, which is formed when carbon dioxide dissolves in water, generally does not produce the aggressive corrosive effects seen with the other acids listed. Thus, nitric acid is the acid that leads to the characteristic yellow discoloration of the stomach mucosa in cases of ingested corrosive agents.
