Detailed Solution

Aluminum (Al) is a commonly used metal in kitchen utensils because it is lightweight, durable, and a good conductor of heat. However, when aluminum comes in contact with water for extended periods, it can react and form aluminum hydroxide, which may further react to form Al⁺³ ions. These ions are more likely to leach into the food when cooking with such utensils, especially if they are acidic foods, like tomatoes, vinegar, or citrus fruits.
