Upon standing silver acquires a black patina, and accurate measurement records an increase in mass. How would you account for these phenomena?
Luna ChenBecause the silver has undergone an oxidation reaction, with the dioxygen in the atmosphere.....
As a result, we increase the metal surface's unnecessary mass.
Silverware gets grimy and blackened when left upright.
At this point, you must instruct the butler to polish, get out his rags, and give the silverware a thorough cleaning; just be sure he does it well.
