Why should curd not be stored in a copper vessel?
Answer and explanation
Correct answer: Acids in curd can react with copper and form harmful salts
The governing concept is the reaction of acids with reactive metals and food-safety precaution. Curd contains lactic acid and has an acidic character. During prolonged contact, the acid may react with copper and produce copper compounds that can contaminate the food and may be harmful in excess. Therefore option A is correct; B and C are impossible, while D falsely denies the acidity of curd.
