What chemical risk is there in storing sour substances in a brass vessel?
Answer and explanation
Correct answer: Acids can react with the metal and form harmful salts
Sour foods commonly contain acids such as acetic, citric, or lactic acid. These acids may react slowly with the copper or zinc components of brass, especially during prolonged storage, producing dissolved metal salts. Therefore option A identifies the relevant food-safety risk. Options B and C have no chemical basis, and option D is unsafe because contact and storage time can permit reaction.
