Why is there a risk of harmful substances forming when lemon juice is stored in a copper vessel?

Answer and explanation

Correct answer: Acid in lemon can react with copper

Lemon juice contains citric acid, so it is acidic rather than basic. Acids can react with metals under suitable conditions; prolonged contact may allow copper to dissolve slowly and form copper-containing salts or other contaminants. This is why acidic foods are not generally stored in unlined copper vessels. The claim that copper never reacts with acids is false, and the other alternatives describe impossible or irrelevant changes. Therefore option A is correct.
