Characteristics of Gold-plated
Gold plating can also tarnish easily if it is subjected to any material that isn’t pH neutral. The pH scale measures how acidic something is. A substance will register as a 7 if it is neutral and less than 7 if it is acidic. (The lowest numbers go to liquids like battery acid, lemon juice, and vinegar.) If a substance is more alkaline than acidic, it will measure up to a 14 on the pH scale (with lye and ammonia ranking high).
*Only solid gold jewelry does not rust or tarnish.
