Why are copper or brass vessels not considered suitable for storing sour substances in the kitchen?
Answer and explanation
Correct answer: Acids can react with metals to form harmful substances
Sour foods commonly contain acids such as acetic, citric, or lactic acid. These acids can react gradually with copper or with components of brass, producing metal compounds that may contaminate the food and can be harmful if consumed. Therefore, glass, stainless steel, or food-safe containers are preferred. Options B and C describe impossible changes, while D is opposite to the chemical reactivity involved.
