Write in brief the corrosion of Al, Zn and Cu in the presence of acidic foods and health hazards.
Aluminium, zinc, and copper can undergo corrosion in the presence of acidic foods.
- Aluminium: Corrosion of aluminium in acidic foods can result in the formation of aluminium ions, which can cause food to discolour and develop an off taste. Prolonged ingestion of aluminium ions can lead to health problems such as Alzheimer’s disease, bone disorders, and kidney problems.
- Zinc: Zinc can corrode in acidic foods, causing it to dissolve and contaminate the food. Ingesting large amounts of zinc can lead to health problems such as stomach cramps, nausea, and vomiting.
- Copper: Copper can corrode in acidic foods, resulting in the formation of copper ions, which can contaminate the food and cause it to develop an off taste. Ingesting large amounts of copper can lead to health problems such as nausea, vomiting, and diarrhoea.
