Toxic metal contamination can occur when acidic foods mix with which metals?

The correct response highlights that acidic foods can react with copper, brass, and tin, leading to toxic metal leaching into the food.

Copper is particularly reactive with acidic substances, which can cause copper ions to dissolve into the food. This is a concern because elevated copper levels can lead to health complications. Brass, an alloy primarily made of copper and zinc, also poses similar risks when exposed to acidic foods, as it can leach out harmful metals. Tin, while typically less reactive, can still be a concern when it is part of can coatings or containers that may corrode in the presence of acidity.

Choosing this answer reflects an understanding of the chemical interactions between acidic foods and specific metals that can result in food safety hazards. Other options include metals like gold and silver, which are noble metals and generally non-reactive, thus posing minimal risk of chemical contamination from acidic foods.
