Transcript of Study of Oxidation on Coins. Oxidation is a chemical reaction that involves the moving of electrons. It is one half of the redox reaction. Redox reactions are concerned with the transfer of electrons between species. The two types of redox reactions are called oxidation and reduction.
Cleaning Antique Bottles Glass. Mineral Deposits: Bottles, vases and other glass objects that have been used to hold flowers or were constantly filled with water can sometimes get a crusty white buildup on the glass surface that is difficult to remove. This buildup is caused by mineral deposits.
The Process of Oxidation. When an atom or compound is oxidized, its properties change. For example, when an iron object undergoes oxidation, it is transformed because it has lost electrons. Unoxidized iron is a strong, structurally sound metal, while oxidized iron is a brittle, reddish powder.
