Because the anodized layer protects it.
Acidic foods will react with aluminum magnesium pans. Acidic foods include tomatoes as well as citrus and many other kinds of fruit.
The "nonreactive cookware" is cookware that does not react with acidic foods. Acidic foods such as tomatoes or wine can react with uncoated cookware made of copper, aluminum, or cast iron. For example, if you put a tomato sauce in an aluminum pot the color of the sauce can change and the sauce will have a slightly metallic taste. When you are cooking with acidic foods you should use pans that are stainless steel, hard anodized aluminum, glass, or that have a coating of tin or enamel. The sale of unlined copper cookware is illegal in many countries, because -- although trace amounts of copper are necessary for good health -- highly acidic foods can dissolve toxic amounts of copper.
These two compounds do not react each other.
No. Acidic foods like tomatoes and oranges are more likely to react with uncoated metal dishes and containers.
Stainless steel, tin lined copper, non-anodized aluminum, clay, enamel, glass, or plastic are all non-reactive. A reactive pan is one made from a material that reacts chemically with other foods, such as aluminum, copper and cast iron. The materials react with acidic foods, imparting a metallic taste and will sometimes discolor light colored soups and sauces a light green or gray! Anodized aluminum has a hard, corrosion-resistant surface that helps prevent discoloration, so it is ok to use. Also, avoid stirring light-colored sauces and soups with an non-anodized aluminum metal spoon or whisk.
Many foods can be made in copper vessels. The only foods that you should avoid making in copper vessels is acidic foods. The copper and acids react and can ruin the food.
A nonreactive saucepan is made of materials that do not react with acidic foods, such as stainless steel or glass. This prevents a metallic taste from developing in the food. In contrast, a reactive saucepan, made of materials like aluminum or copper, can react with acidic foods, altering their flavor and appearance.
Foods that are acidic, alkaline, or high in salt can react with magnesium and aluminum pans, causing them to leach into the food and affect its taste. Examples include tomatoes, citrus fruits, vinegar, and salty foods. It's best to avoid cooking these types of foods in magnesium and aluminum pans to prevent any potential reactions.
Foods that are acidic, such as tomato sauce or citrus fruits, can react with stainless steel and cause discoloration or leaching of metals into the food. It is recommended to avoid prolonged contact between these types of foods and stainless steel cookware to prevent any potential reactions.
Cast iron will react to acids in foods. Normally this won't be a problem if the cookware is properly seasoned and oiled. That applies to when you are actually cooking. But never store food -- especially with any acid content at all long-term in cast iron as the food will absorb the seasoned layer, and if highly acidic with then taste metallic.
It is expected that the chemical will become reactive as it becomes basic. It may also react when it becomes acidic.
Yes, silver can react with sulfur compounds present in foods like curd, leading to tarnishing or discoloration of the silver. It is best to avoid direct contact between silverware and acidic foods like curd to prevent any unwanted reactions. Regular cleaning and maintenance can help preserve the appearance of silver items.
