What is the most evident symptom of poisoning by sulfuric acid?

1. Severe abdominal pain

2. Black vomit

3. Difficulty breathing

4. Skin burns

The correct answer is: Black vomit

The most evident symptom of poisoning by sulfuric acid is skin burns. Sulfuric acid is a highly corrosive acid, and direct contact with the skin can cause immediate reactions, including severe burns. These burns can vary in severity depending on the concentration of the acid and the duration of contact. The presence of burns is a definitive indicator of exposure to sulfuric acid and signals the urgent need for medical intervention. While severe abdominal pain, black vomit, and difficulty breathing can also occur from various types of poisoning or chemical exposure, they are less directly associated with sulfuric acid. Abdominal pain might arise if the acid is ingested, and difficulty breathing could result from inhalation of fumes. Black vomit is not a typical symptom related to sulfuric acid poisoning, as it is more commonly associated with gastrointestinal bleeding or the presence of certain toxins. Each of these symptoms can be serious, but skin burns uniquely signify the corrosive effects of sulfuric acid and highlight the immediate dangers posed by contact with this substance.
