Why is it unsafe to store curd in a copper vessel?

Answer and explanation

Correct answer: Acids in curd can react with copper

Curd contains lactic acid and is therefore acidic. If it is stored for a considerable time in a copper vessel, the acid may react with the metal. Such a reaction can form copper compounds that contaminate the food and may be harmful when consumed in excess. Copper does not convert curd into water or sweetness, and the statement that curd has no acid is incorrect. Hence option A is the safe and chemically relevant explanation.
