Tarnish on silver is predominantly silver oxide and/or silver sulfide, both of which are insoluble in water. Magnesium, in accordance with its position in the electromotive series much higher than silver, displaces metallic silver from these compounds back onto the surface of the silverware. leaving behind oxides and/or sulfides of magnesium, which are sufficiently soluble in water to be easily washed away. This reaction is greatly facilitated if the tarnished silver and the magnesium are placed in contact with one another in an electrolyte solution in water.
