because it's cannot oxide se

Answer 2

Answer:

Food shouldn't be stored in copper vessels as copper gets corroded when exposed to moist air containing carbon dioxide. It gets coated with a blueish-green deposit called Basic copper carbonate. This is very harmful and poisonous for our body.

Food can be stored in aluminium vessels. But acidic food like lemon pickles etc. cant be stored in it as the acid in the food reacts with aluminium and creates poisonous acids.
